The In-Line Filter Holder is a 0.5″ diameter in-line filter holder with SMA-905 connection on each end to connect to your spectroscopy system set-up. The In-line Filter holder was initially designed to allow customers to increase system dynamic range by reducing signal intensities to their detector. Easily stack required optical filters into the holder to adjust your signal.  Popular filters include Neutral Density, Diffuser, Fluorescence Bandpass, and Longpass.  Feel free to purchase the filters direct from us or use your favorite optical filter supplier!

Color Equalization Filter (CEF) – Special filter for red light suppression of halogen lamps. Great for use with our SL1 when performing a colorimetry measurement. SL1-Filter comes with the CEF installed.

Fluorescence Bandpass Filters – 1/2″ diameter optical filters for fluorescence spectroscopy.  Engineered for common fluorescence agents used in many imaging applications. Featuring >90% transmission and >OD 6 blocking outside of the pass band.  Contact our team for specific wavelength requirements.

Longpass Filters – Longpass Edge Filters are designed to transmit wavelengths greater than the cut-on wavelength of the filter. StellarNet can provide a variety of longpass filters depending on your spectroscopy application.
