Heat Control

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

HM-VS-1150 Hot mirror

These "hot mirror" filters transmit the visible spectrum and reflect the infrared at 0 degrees. The average transmission is more than 93% from 425 to 675 nm. The average reflectance is more than 95% from 750 to 1150 nm. Custom angles of incidence can be designed to specification

HH-VIS-1600 Hot Mirror

Extended Hot Mirror filters transmit the visible spectrum and reflect the infrared at normal incidence. The average transmission is specified to be more than 85% from 425 to 675 nm and average reflectance is more than 90% from 750 to 1150 nm & 80% from 1150-1600 nm. Custom angles of incidence can be designed to specification

HM-UV-1050 UV pass Hot Mirror

UV Hot Mirror filters are specially designed to transmit more than 80% on average from 245-460 nm and reflect more than 70% in average from 800-1050nm at normal incidence. Custom angles of incidence can be designed to specification

CM-VS-STD- 45 degree Cold Mirror

Cold mirror filters reflect the visible spectrum and transmit heat (infrared) at 45 degrees. The average reflectance is more than 95% from 425 to 650nm. Transmission is more than 85% average from 800 to 1200 nm. Custom angles of incidence can be designed to specification

UV Cold Mirror

Cold Mirror filters are specially designed to reflect more than 95% average of ultra-violet rays from 350-450 nm and transmit more than 90% average 550 -1200nm at 45 degrees angle of incidence
