MidOpt Filters Where Image Quality Begins - Site ftp Elvitec

Visible Light Bandpass Filters
• Designed for use with commonly utilized LED light sources/UV-excited
fluorescence wavelengths
• Bandwidth 80-90 nm (+/- 10 nm) FWHM
• Shields systems from unwanted ambient light
Bandpass Filters
• Enhance contrast for improved viewing of desired features
• Improve resolution (chromatic aberration correction)
• Test to determine the appropriate lighting for an application
• Suitable for laser diodes
