NUV Plan APO Lens
Seiwa Optical
These objective lens extends that range of the M Plan APO objectives into UV and have a super long working distance. The focal plane is corrected for both Bright Field and Near UV (355nm), meaning that both wavelengths will be in focus.

PEIR 2000 HR Series Lens
Seiwa Optical
Seiwa PE IR 2000HR Series lens are color corrected from 1000nm-2000nm wavelength. It’s high resolution and high throughput design enables collection of weak signals from samples without re-focusing. In addition, this lens is able to correct 0-700 micron thickness of silicon and glass. Both 20X (NA:0.6) and 50X (NA:0.7) are available.
