Bandpass filters

A bandpass filter will block shorter and longer wavelengths, resulting in improved contrast and better control over changes that may occur over time in ambient lighting conditions.

Availability:

       - Red bandpass - 635nm

       - Green bandpass - 525nm

       - Blue bandpass - 470nm

Polarizing filters

 
Polarized light is defined as vibrating in only one such direction. A polarizing filter passes light through in only one vibratory direction. It is generally used in a rotating mount to allow for alignment as needed. In our example above, if it is aligned perpendicularly to the plane of vibration of the polarized reflected glare, the glare will be absorbed. The light source must be polarized too.

Our polarized filters carry a fixing screw to avoid possible rotating movements in its position.
