The spectral response of silicon extends into the visible light range. This makes sensors vulnerable to ambient light; particularly
from tungsten sources (or the sun) where red light is present. Many of OPTEK’s slotted optical switches shield the sensor in an
opaque housing designed to control ambient light. External light filters or controlled modulation of the LED and/or sensor may
also be used to reduce the noise from ambient light. As another alternative, most photographic shops can supply infrared
passing gelatin filters for laboratory experimentation. For production use, several types of plastic are commercially available with
varying degrees of infrared and visible transmissivity (e.g., polysulfone and polycarbonate).
The product specifications in this book were written with ease of design in mind. Emitter output and sensor response levels are
specified in terms of milliwatts per square centimeter at separation distances typical for most applications
While the OPTEK line is among the industry’s broadest, a unique application requirement may result in the need for custom
selection or package design. Call your local OPTEK sales office for more information.
OPTEK provides product bulk packed in bags, tubes, trays, tape and reel or tape and ammopack. All products are inspected by
OPTEK based on OPTEK packing requirements as well as EIA-468 when applicable. Add “TR” suffix for tape and reel. Add “TA”
suffix for tape and ammopack. Tape and real or tape and ammopack are not available on all device types, for more information
call your local representative.
