To avoid disturbing reflections, the LP−750 can be put directly on CCD−or CMOS−sensors. For purposes of illumination it is also available with a dimmed anti−reflex coating.
Another advantage of this filter is its simple way of processing: it can get slit to brake it. Another possibility is jet cutting which we offer at larger numbers. Herewith, (almost) every dimension can be realized.
The LP750 is available in four thicknesses. The following standard sizes can normally be delivered from stock. Different sizes have delivery times of 1-2 weeks.
