Hot Mirrors Hot Mirrors and Cold Mirrors

Our steep-edge long pass filters employ magnetron sputtered hard oxide coatings to yield deep rejection and a sharp transition to very high transmission. The coatings are deposited on precision polished Fused Silica substrates, and do not employ any absorbing filter glasses, making them suitable for... [See More]

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 425-675nm and average reflectance is more than 90% from 75o-1150nm and 80% from 1150-1600nm. Custom angles of incidence can be...

Dichroic Filters for Every Application. A dichroic filter is thin optical filter crafted to transmit light in only one narrowly defined wavelength band, while reflecting all other wavelengths. These optical filters are also known as thin-film or interference filters. Dichroic filters are typically... [See More]

The 20HMS-0 Hot Mirror is a 50.8 x 50.8 mm square 0 ° mirror used as a heat control filter. Our hot mirrors are heat-reflecting shortpass filters designed to transmit 420-690 nm visible wavelengths while reflecting 725-1550 nm near-infrared heat generating wavelengths. These filters can be used... [See More]

Hot Mirrors perform as their name states: they reflect the heat and transmit the visible light. All of the coatings are classified as hard, first-surface dielectric, and will meet or exceed the specified humidity and abrasion specifications. To prevent cracking or crazing from high heat...

• Thickness: 3

• Filter Diameter, Side Length, or Rectangular Length: 12.5

These filters are very similar to the Hot Mirrors with the exception of their longer IR blocking range. This extended blocking range is achieved by a combination of reflection from the dielectric stack and absorption from an IR absorbing filter glass. Due to this absorption factor, these filters are...

Hot Mirrors are used in applications when there is the requirement to separate visible light from heat. The hot mirror accomplishes this by reflecting the heat. The use of Borosilicate type glass allows operation in high temperatures. Operation at an AOI of 0 º is preferred. The most common... [See More]
