250nm Deep to Near UV Bandpass Filter

Bandpass Filter

Description:

The 250nm Near-UV Bandpass Filter for Machine Vision is a very broadband UV filter, mainly intended for deep-UV imaging. It is the only filter available that offers excellent visible and near-IR blocking (≤0.1% abs. ≥400nm; ≤0.06% abs. ≥415nm), thus making it best suited to distinguish features or characteristics that are only visible under UV illumination.

Offered in a limited number of sizes, and not intended for use with standard CCD/CMOS cameras that do not image deep into the UV spectrum.
