Optical filters
LOT-QuantumDesign can supply a large variety of optical filters. Our product range includes:
Bandpass filters – covering the UV-VIS-IR with standard sizes including 12.5 mm, 25.0 mm
and 50.0 mm diameter.
• Neutral density filters – both absorptive and reflective, OD from 0.1 to 4.0
• Hard-coated metallic UV filters – for use with higher intensity light sources
• Edge filters – short and long pass, order sorting filters for monochromators
• Heat control filters – hot mirrors, water filters
• Raman filters – notch filters, super notch filters, edge filters
OPTICS Additionally, we have complementary products such as threaded filter rings, stand-alone
• Fluorescence filters

motorized filter wheels and room-temperature curing, optically clear, electrical grade epoxy.

Liquid crystal tunable filters
LOT-QuantumDesign can provide a range of tunable imaging filters, based on liquid crystal
technology, through the Perkin Elmer brand. The VariSpec electrically variable filters benefit
from high optical throughput and large aperture sizes; meaning they are particularly suited
for use with VIS or NIR cameras or integration into hyper- or multi-spectral imaging setups.

Features:
• Solid state design for rapid, vibration less tuning
• USB interface
• VIS, NIR and SWIR models
33 • 20 or 35 mm aperture
• Adapter kit for standard mounts (C-mount, T-mount)
