W-VIEW GEMINI Image Splitting Optics
The W-VIEW GEMINI is an image splitting optics which provides one pair of dual wavelength images separated by a dichroic mirror onto a single camera. Simultaneous image acquisition of dual wavelength images allows you high speed ratio metric imaging and other multiple fluorescence applications.
The W-VIEW GEMINI provides excellent transmittance across a broad range of wavelengths. Exceptional performance from 400 nm to 800 nm is enabled by our proprietary lens system. When used with "imaging grade" filters, the system is optimized for low light imaging.
The W-VIEW GEMINI is designed to take advantage of the wide field of view provided by sCMOS cameras. Up to 13 mm × 6.4 mm F.O.V. and resolution of up to approximately 2000 pixels × 1000 pixels for each image.
Because it is compatible with commercially available filters, the W-VIEW GEMINI allows for great wavelength flexibility. Choose the dichroic, bandpass and neutral density filters that work for your experimental question.
Our "Bypass mode" means that by simply removing the dichroic mirrors, the camera sees the image as though it was connected directly to the microscope. You can switch between standard imaging and dual wavelength imaging without having to reconfigure the camera or remove the W-VIEW GEMINI.
The W-VIEW GEMINI has a correction lens unit in the long wavelength path and it can improve the magnification difference of two wavelength images caused by chromatic aberration. The right images show an example of the magnification difference caused by chromatic aberration is improved by the correction lens unit.
Designed for stability on both inverted and upright microscopes, the W-VIEW GEMINI's C-mount connectors are placed along a linear axis. And with its compact form factor, it integrates smoothly on a wide range of research microscopes.
The W-VIEW GEMINI is designed to be easily adjusted when used with any camera. And, when using a Hamamatsu camera, the included "W-VIEW Adjustment" software makes the process even faster by simultaneously displaying and magnifying nine strategic points on the concentric chart (also included). This visual feedback lets the user dial in alignment quickly and accurately.
