Heat control filters are a special type of dichroic
filter used to remove unwanted energy from the light emitted by a source.
A common example is the use of hot mirrors in very bright spotlights used
in entertainment applications. Heat control filters are able to separate
the unwanted infrared, perceived as heat by people, from the visible light
desired.

HM-VS-950
Hot mirror
Hot Mirror filters transmit the visible
spectrum and reflect the infrared at normal incidence. The average
transmission is specified to be more than 93% from 425 to 675 nm and
average reflectance is more than 95% from 750 to 950 nm. Custom angles
of incidence can be designed to specification |
