• High Transmission for Detecting Weak Signals
• Deep Blocking for Maximum Laser Rejection
• Ideal for Raman Spectroscopy or Life Science
Instrumentation
TECHSPEC® Raman Longpass Edge Filters are single filter solutions
for reducing spectral noise in Stokes shift applications. These filters
are designed to create sharp transitions between transmitted Raman
signals and blocked laser wavelengths. Designed to detect even the
smallest Raman shifts, TECHSPEC® Raman Longpass Edge Filters
are ideal for integration into Raman spectroscopy or confocal microscopy
systems. The hard coated design offers superior transmission
characteristics than comparable traditional coated filters.

• Ultra-Thin, Flexible Substrate
• Sharp Cut-On Wavelength Designs
• Extruded Thin Film, Insensitive to Scratches
Ultra-Thin Flexible Longpass Filters combine high performance and low cost in a new class of thin film
interference filters that are flexible, scratch insensitive, and ultra-thin (200 - 500 μm). These filters feature
cut-on wavelengths in the visible range with cut-on tolerances of ±3% and > 85% average transmission.
The flexible extruded thin film filters are complex multilayer filters, which excel across a variety of needs,
including longpass, edge, and notch filters. Ultra-Thin Longpass Filters are ideal for demanding vision and
medical technology applications.
• Flexible Design to Conform to Curved Surfaces
• Scratch Insensitive, Ultra-Thin Polymer Construction
• > 80% Average Transmission
Ultra-Thin Shortpass Filters are constructed from layers of ultra-thin polymers and dyes that deliver the same
performance as thick traditional filters but in a compact, flexible filter design. The all-plastic composition of
these flexible shortpass filters makes them both shatter proof and insensitive to scratching. Less than 500 microns
thick, these flexible filters provide high transmission and a blocking optical density (OD) of 2,0 outside
of transmission range. Ultra-Thin Shortpass Filters are available with sharp cut-off wavelengths across the
visible and near-infrared (NIR) spectra. These filters are an excellent solution for vision or medical applications
requiring low cost, space saving optical filters.
