W-VIEW GEMINI-2C Image Splitting Optics
Dual channel optics are simple… in principle. In practice, designing a device that enables quick, stable alignment and delivers images with minimal distortions over a large field of view requires attention to detail. The W-VIEW GEMINI-2C gets the details right and more. Building on our imaging and optical experience, the W-VIEW GEMINI-2C is the first dual camera, dual channel system engineered with super resolution quality, while simultaneously offering versatility, expandability and ease of use. The W-VIEW GEMINI-2C turns a simple optical concept into an elegant and useful tool that can help maximize the information content of every image acquisition.
Using custom designed optics, our engineers fully optimized system performance, offering super resolution quality by minimizing point spread function (PSF) degradation, field curvature and wave front aberration
Maintaining optical quality at the edges of the field demands extra care. The W-VIEW GEMINI-2C delivers excellent performance over the entire field of two ORCA-Flash4.0 sCMOS cameras and diffraction-limited performance within the center 12 mm diameter FOV.
This unmatched level of optical performance delivers bright, even, chromatic aberration-corrected images to both cameras.
The W-VIEW GEMINI-2C makes alignment easy and stable. Included alignment software provides direct visual feedback when using Hamamatsu cameras. An optional grid chart fits directly into the primary imaging plane making it possible to align images in the absence of feedback at the sample position.
All filter and beamsplitter holders are designed to industry standard specifications, allowing researchers to freely choose their optical components.
It’s easy to bypass all the optics of the W-VIEW GEMINI-2C, simply remove the filters and beamsplitter and insert the port covers. In addition, by using a 100 % mirror instead of a beamsplitter, the W-VIEW GEMINI-2C can be used to switch between two different cameras.
With input and output C-mounts, the W-VIEW GEMINI-2C is compatible with and easily attached to standard inverted microscopes.
Ask any microscopist how to improve image quality and they will recommend using a high NA objective. The trade-off for these optically beautiful images is depth of field. The Extended Focus Device, a new optional feature for our W-VIEW GEMINI-2C, efficiently extends your depth of field up to 5 times by using a simple optical filter.
