Enhance viewing of subjects illuminated by a 450nm blue LED or laser light source.

MidOpt® introduces the BP450 Indigo Bandpass and the BN450 Narrow Indigo Bandpass, two new filters designed for multi-application use.

The MidOpt BP450 Indigo Bandpass Filter is commonly used in fluorescence applications with an emission ranging from (430-460nm). It is suitable for use with LED or laser diodes with higher than normal ambient lighting conditions.

Blue LED Illumination and UV Excited Blue Fluorescence Applications:

The BP450 is an excellent choice for enhancing viewing of subjects illuminated by a 450nm blue LED. For UV Fluorescence applications, its broad bandwidth and high peak transmission results in significantly brighter, higher contrast images.

Blue Laser Applications:

The BN450 Narrow Indigo Bandpass is a great choice for use with 3D blue laser triangulation systems used for measuring position, distance, level, displacement, proximity and profiles of objects. This also includes industrial process automation and control, as well as for test and measurement in process monitoring and validation. It is also highly-effective when used in applications with higher than normal ambient lighting conditions.

StableEDGE® and A/R-Coated:

As with all MidOpt Bandpass filters, the BP450 and BN450 are both manufactured with MidOpt StablEDGE® technology making them less sensitive to angle of incidence variations than traditional interference filters. They are also both coated with the MidOpt BBAR Anti-reflection coating. Both filters are available with standard lens mounts ranging from 13.25mm to 105mm. They are also available in unmounted sizes up to a 165mm square
