Tuning Element
Elk Industries, R-K ManufacturingRequest Info
The Tune-a-Flex element from Elk Industries LLC acts as a color
filter. It looks like an ordinary piece of glass but, when held up to a light, “filters”
light into a red color. When the plate is tilted, from one angle to another and
in the same plane, it changes color from deep red to bright green. Guaranteed efficiency
is >90% and, typically, ≥95%. There is no refractive activity to cause problems
for imaging applications. Five types cover five spectral ranges, which can accommodate
the entire visible wavelength range, with some overlap. With Tune-a-Flex, a single
element can be used to allow narrow-linewidth tuning with high efficiency. For use
in polymer or polystyrene dye lasers, it affords the user a greater range of applications
than the typical broadband outputs available without a tuner.
