These plano-plano windows effectively shield telecentric lenses from the outside environment without affecting the quality of your imaging system because they do not cause changes in optical magnification. WI series is also compatible with CMMR mirrors, preserving the delicate optical surfaces from dust or other hazardous particles.

Each window is complemented by its own CMWF holder which features a precise tightening knob that allows for easy and secure clamping. CMWF holders are needed to mount WI protective windows in front of telecentric lenses and must be ordered separately.

KEY ADVANTAGES

Protection from dust, debris or other hazardous particles.
No change in optical magnification.
Compatible with telecentric lenses, LTCLHP illuminators and CMMR mirrors.

CMWF mounting mechanics required (must be ordered separately). When a WI window is placed in front of a lens, its working distance increases of approximately ⅓ of the window thickness.

CMHO series clamping mechanics may be used prior to verification of mechanical compatibility (see CMHO series mechanical drawings available online). CMHO is not compatible with the combination of the following: WI + CMWF assembly and TC13xxx.

Ordering information

When ordering, include the following two items:
- WIxxx protective window/filter
- CMWFxxx holder

For example, if you need a protective window for a TC12036 telecentric lens, you have to order both the following items:
- WI036 protective window
- CMWF036 holder

The CMFW holder is not required when interfacing WI windows with CMMR mirrors.

Notes

CMWF mounting mechanics required (must be ordered separately). When a WI window is placed in front of a lens, its working distance increases of approximately ⅓ of the window thickness.
