Nikon confocal microscope system A1+ provides high-resolution imaging of up to 4096 x 4096 pixels with a galvano (non-resonant) scanner. With diverse innovative optical and electronic technologies, such as the VAAS pinhole unit, superior image quality has been achieved.

High-resolution imaging with a galvano scanner

The A1+'s galvano scanner enables high-resolution imaging of up to 4096 x 4096 pixels. In addition, with the newly developed scanner driving and sampling systems, plus image correction technology, high-speed acquisition of 10 fps (512 x 512 pixels) is also possible.

Increased light detection efficiency realizes high image quality

The low-angle incidence method utilized on the dichroic mirrors increases fluorescence efficiency by 30%.

By employing the hexagonal pinhole, higher brightness equivalent to that of a circular pinhole is achieved.

Nikon's original dual integration signal processing technology (DISP) has been implemented in the image processing circuitry to improve electrical efficiency, resulting in an extremely high S/N ratio.

VAAS pinhole unit for bright, clear images

Nikon has developed an original confocal microscopy VAAS (Virtual Adaptable Aperture System, option) that can eliminate flare while retaining image brightness. Because of the deconvolution of the light that passes through the pinhole and the light that does not pass through the pinhole, acquisition of brighter images with less flare is possible. Different sectionings (slice thicknesses) can also be simulated after image acquisition.

Enhanced spectral imaging

High-speed spectral imaging

Acquisition of a 32-channel spectral image (512 x 512 pixels) with a single scan in 0.6 second is possible. Moreover, 512 x 32-pixel images can be captured at 24 fps.

Accurate, high-speed unmixing

Accurate spectral unmixing provides maximum performance in the separation of closely overlapping fluorescence spectra and the elimination of autofluorescence. Superior algorithms and high-speed data processing enable real time unmixing during image acquisition.

Simultaneous excitation of four lasers

Three user-defined laser shields allow simultaneous use of four lasers selected from a maximum of nine colors, enabling broader band spectral imaging.

V-filtering function

Filter-less intensity adjustment is possible by selecting desired spectral ranges from 32 channels that match the spectrum of the fluorescence probe in use and combining them to perform the filtering function.

Simple operation of complex applications

NISĪŅElements C control software enables integrated control of the confocal imaging system, microscope and peripheral devices with a simple and intuitive interface. Diverse reliable analysis functions are also available.
Basic operation Optical setting

System integration of Ti-E inverted microscope for multi-mode imaging is possible by equipping the confocal microscope system with N-SIM/N-STORM super resolution microscope system, TIRF system, spectral detector and Perfect Focus System. All systems can be controlled by a single NIS-Elements platform.
