Optolite IR (infrared) broad band acrylic filters have been specially
formulated to transmit infra red radiation at wavelengths greater
than approximately 750nm and are thereby virtually opaque to visible
light.
Optolite IR (infrared) is eminently suitable for use in photometric
systems which are triggered by near infrared signals but which
must operate in environments with high levels of visible radiation.
Optolite IR (infrared) eliminates the visible spectrum and so improves
the effectiveness of the system by increasing the signal-to-noise
ratio.
Specific applications include remote controls, security systems,
presence sensing devices, proximity sensors and scanners.
Optolite IR Transmission Characteristics
Features include:
• Excellent
Transmittance up to a maximum of approximately
90% in the infra red region from 850nm – 2000nm,
50% transmission at 780nm and effectively 0% below 740nm in the
visible spectrum.
• Cast-in Non-Glare Finish
available as an option to cut down any unwanted front surface reflections.
• Filters supplied to
Customer Drawings in standard thicknesses
of 0.5, 1.0, 1.5, 2.0, 3.0mm.
Other, non-standard thicknesses and tight tolerances
can be supplied to order.
Instrument Plastics Limited has a policy of
continual improvement of products and so reserve the right to change
the product specification without notice.
