Description
Introduction of Bote Ultra Narrow Bandpass Filters
Ultra-narrow band filters are ideal for use as laser lines, laser cleanup, or laser excitation filters in applications such as fluorescence microscopy, flow cytometry, and DNA sequencing. They are also highly resistant to laser damage, ensuring they maintain high levels of performance over time.
Depending on the wavelength range and requirements of your system, Bote narrow band interference filters can be custom designed to meet one or more of the following challenging specifications:
ØUp to 98% peak transmission
ØDesign blocking up to OD10
ØCWL at any wavelength from UV to NIR (~250 nm to 1800 nm)
ØCWL tolerance as small as 0.05 nm
ØFWHM bandwidth as narrow as 0.1 nm
ØTWE measured as low as 0.01 wave RMS/inch at 632.8 nm
