InfiniProbe TS-160

If you are reading this, you probably use zoom microscopes or macro lenses. Until now, you could use a zoom microscope in your lab or take a macro lens into the field. It was either/or. No longer. InfiniProbe TS-160 is a small wonder that weighs as little as 292g [10.3 oz], focuses internally, and (once configured) never changes its dimensions or balance.

The TS-160 is the latest in the InfiniProbe¢â Series from Infinity Photo-Optical. Like all InfiniProbes, the TS-160 can focus from infinity to only millimeters from an object. Unlike any of the other InfiniProbes, TS-160 can be used directly with almost any digital or video camera?all while producing world-class images comparable to the best zoom microscopes that do not directly cover formats up to 35mm. It is a universal format system.

The TS-160 System

The TS-160 consists of a Main Body which contains a patent-pending internally-focusable optical system, activated by a Focusing Ring which turns 360-degrees. Inside is a provision for 25mm diameter filters (for example, polarizers or fluorescence types). At its rear are two ganged T24mm tubes (three ganged T24 tubes when the MICRO HM Objective is used in 35mm format?see below) which allow access to accessories when one is temporarily removed?or permit one to be exchanged with a mount for use on a stereo microscope stand. A Clamp is available so that the TS- 160 can be mounted on tripods or fixtures via 1/4-20 or two "outboard" M4 taps. A Variable Iris allows contrast control.

Two Lenses in One

Two objective lenses interchange and attach to the Main Body: MACRO and MICRO HM:

  1. The MACRO Objective is compact and can be focused from infinity (equivalent to a c.155mm F.L. 35mm camera lens) down to 18mm. When attached to the TS-160's Main Body, it provides a magnification range of 0-4x. Used with DSLRs or other viewing cameras the image is seen upright, as is typical of taking lenses.
  2. The MICRO HM (Highest Magnification) Objective can be focused from infinity (equivalent to a c.60mm F.L. 35mm camera lens) down to 18mm. When attached to the TS-160's Main body, it provides a magnification range of 0-16x when two T24 tubes are ganged for use up to 4/3-in. formats and 0-18x when the third (supplied) T24 is added for 35mm format uses (see below). Used with DSLRs or other viewing cameras, the image is inverted, as is typical of microscopes.

Whichever objective you choose, the TS-160 is like taking a large lab-type zoom microscope with you into the field. Except, the InfiniProbe TS-160 can be picked up in your hand and carried wherever you go.

Never Lose Sight of Your Subject

The InfiniProbe TS-160 is not a zoom lens. It is a continuously-focusable microscope. This means you can focus on a circuit board, insect, forensic scene?or any other suitable object at a distance and move in to see it become a single frame at great magnification. Instead of being limited to a single working distance, you can choose whatever standoff you wish. You will never lose sight of your object as you focus closer and closer. As you focus, detail (resolution) increases and depth of field gets shallower. If you need more depth of field, just back up to get what you need. The depth of field and magnification are then balanced for best results.

Easy to Use

Using the TS-160 is as natural as stepping closer to get a better look. But the best results are achieved by understanding the proper use of the Variable Iris incorporated in the Main Body.

Because the TS-160 is a microscope and not a "taking" or typical "macro lens," its Variable Iris is analogous to that of a regular laboratory compound microscope's iris in the condenser. Like lab scopes, there are no f/stops to be found?they are irrelevant. The Variable Iris' real purpose is not to control exposure?but to control contrast and field flatness. In the same way that lab scopes are not supposed to be used with the condenser full-open, the TS-160 is not supposed to be used full-open either. The proper use of the condenser on lab scopes is to stop-down the until the first change in contrast "jumps" as the condenser's iris is closed-down?virtually an "automatic" characteristic. Consequently, the TS-160's Variable Iris is used to set the cross-over point where contrast and resolution are best-matched. This means that when the TS-160 is used correctly, all you have to do is: 1) Focus; 2) Set the contrast "jump;" 3) "Click." The camera or flash then sets the proper exposure. Perfect results from the TS-160 are as easy as that.

Depth of Field

Forget the typical technique of stopping-down the iris to gain depth of field. Simply move the TS-160 a bit higher up and refocus. At a certain point, the exact balance of depth of field and resolution can be selected. This feature allows you to determine the best image to capture. You can digitally enlarge "just a bit" later, knowing that you have captured all the detail and depth of field.

CentriTel¢ç Compressor/C

The TS-160 is designed primarily for large formats. However, if C-mount cameras up to 2/3-in. format are used, its magnification may be too high to match their pixel sizes. Projected image elements falling over several pixels can actually cause less resolution at the camera's sensor. The CentriTel Compressor/C answers this need and fits inside the TS-160 on top of the Filter Holder (see photos). When configured with the CentriTel Compressor/C, the TS-160 is remarkably compact. A supplied T16 Tube parfocals both the MACRO and MICRO HM Objectives with their standard ranges, reducing their magnifications to 0-2x and 0-8.2x, respectively (overall, about a 50% reduction factor). The resolution of the TS-160 is then matched for C-mount cameras. Of course, the standard magnifications are still available if the CentriTel Compressor/C is removed and the unit brought back to its original configuration.

In addition, the CentriTel Compressor/C adds Infinity's unique CentriTel capability to the TS-160 when used with C-mount cameras. The magnification remains essentially constant during translation by the TS-160's internal focusing system. This makes the CentriTel Compressor/C ideal for digital stacking techniques from a fixed position.

The InfiniLight Adapter mounts on the TS-160. It allows the use of most commercial flash and ring lights by means of a series of plates that mount on the adapter itself. Shown are some suggested configurations.

Finally, Someone Is Bound to Ask...

"If the TS-160 can be used as if it were a 'TS-180', why not call it TS-180?" The answer is similar to the old adage that a "square is a rectangle but not all rectangles are squares."

The TS-160 works well even if used with two T24 spacers with the MICRO HM Objective?but not as well as it can be if an additional (supplied with each unit) T24 is added. (The MACRO always works with only two-ea. T24 spacers?not an issue). Essentially, if one is out in the field with the MACRO and wants to quickly switch to the MICRO HM Objective without taking apart the system?he can. 35mm can be covered but at a very slight compromise in outer field flatness. And, for C-mount use, the TS- 160 is best with only two of the T24 spacers in-system. So, "160" (up to 16x) is always possible in all cases. "180" (18x) is only advantageously possible with 35mm format?and only really useful for 35mm. It is better to keep smaller formats less projected onto the sensor in view of their pixel sizes. Consequently, "160" (16x) is possible with two T24 tubes in all formats and "180" (18x) is optimized for only one. We decided to keep the product named for its most versatile configuration.

The Universal Imaging Solution

Not your average macro lens! Shown: The TS-160 mounted horizontally with Beam Splitter to image an outside object into a microscope objective's field. This unit was supplied to a Nobel Prize winning laboratory to solve one of
their most difficult problems.

InfiniProbe TS-160 represents a universal solution for digital and large format imaging?all in an extraordinarily compact unit. It defies comparison with the best zoom microscopes in terms of the imagery it produces. Yet, the TS-160 is far more cost-effective. With the InfiniProbe TS-160, you can take it with you. Or, you can mount it on a stand in your lab.
