Hamamatsu W-View Gemini-2C Image Splitting Optics

Building on Hamamatsu's 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.

Hamamatsu W-View Gemini-2C Image Splitting Optics

Custom Designed Lenses Optimized for Fluorescent Imaging

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.

Wide Field of View (20 mm for standard imaging, 12 mm for diffraction-limited imaging)

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.

Ultra-Low Distortion (0.05%), High Spatial Uniformity (98%), High Transmission (98 % @ 450 nm to 800nm)

This unmatched level of optical performance delivers bright, even, chromatic aberration-corrected images to both cameras.

Dual Channel x, y, z and Rotational Alignment

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.

Standard Filters and (Dichroic) Beamsplitters

All filter and beamsplitter holders are designed to industry standard specifications, allowing researchers to freely choose their optical components.

Bypass and Camera Switching Mode

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.

C-mount Compatibility

With input and output C-mounts, the W-View Gemini-2C is compatible with and easily attached to standard inverted microscopes.

Tri-Color and Quad-Color Imaging

The 4f configuration of the optics makes it possible to connect multiple W-View Gemini-2Cs for full-field, tri-color, threecamera imaging. Alternatively, the addition of two single camera W-View Gemini devices provides quad channels imaged onto two ORCA-Flash4.0 series cameras.
