 If you have equipment operated by or using near infrared signals within environments with high levels of visible radiation then you will need to consider one of our infrared filters. Within an environment with high visible radiation infrared operated equipment without an infrared filter may malfunction or be activated accidentally. Such equipment using infrared filters can include remote controls, security systems, presence-sensing devices, proximity devices or scanners.
Our Optolite Infrared (IR) broadband acrylic filters are carefully designed to transmit infrared radiation at wavelengths greater than 750 nanometres (nm), meaning that the signals are all but opaque to visible light. Instrument Plastic's Optolite infrared filters cut out the visible spectrum and thereby improve the system’s effectiveness by heightening the signal-to-noise ratio. If you are looking for an infrared filter that provides excellent transmission then look no further. With one of our infrared filters, 90% of your infrared signals within the region of 850nm and 2000nm will reach the intended target.
Our infrared filters can be created with a special cast-in non-glare finish. This means that your IR equipment will not have any unnecessary surface reflections that could cause unwanted behaviour. As our non-glare finishes are cast-in it also means that they cannot be peeled, scraped or scratched off unlike simple coverings and other similar infrared filter solutions.
Finally all of our infrared filters are custom-made to your specific requirements. You can simply send us a drawing and we can build the shape and size of infrared filter that you need. Our infrared filters also come in standard thicknesses of 0.5, 1.0, 1.5, 2.0 or 3.0mm depending on your needs. However, as we realise that every one of our customers is different, we can also provide non-standard thickness infrared filters built specially to order.
Optolite Infrared Filter Transmission Characteristics
Features include:
- Infrared Filters have 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.
- Infrared Filters have a Cast-in Non-Glare Finish available as an option to cut down any unwanted front surface reflections.
- Infrared 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.
