Dielectric Longpass and Shortpass Optical Filters

High performance filters for a range of spectroscopy measurements

Overview | Specifications | Gallery | Related Products | Resources and Support

Optical filters from Ossila are available as longpass or shortpass in a range of wavelengths. The filters are perfect for isolating regions of the electromagnetic spectrum for fluorescence measurements, absorption measurements, and more.

Our filters have >90% transmission in the region of transmittance and are OD4 in the suppressed region (~0.01% transmission).

Each individual filter is housed in an outer ring to aid in handling and enhance the OD through prevention of scattering. The ring is labelled with the cut-on/off wavelength and whether the filter is long or shortpass.

You can also buy our optical filter set, which includes either the longpass filters, shortpass filters, or full range.
