General Description
Shape Optics Technologies Pte Ltd (SOT) offers high-performance Hot Mirrors designed to separate visible light from infrared radiation. These optical components reflect heat-generating IR wavelengths back toward the source while allowing visible light to pass through to the target.
Hot Mirrors are widely used in optical systems where thermal management is critical, such as laser platforms, digital projection systems, and imaging instruments. By minimizing IR-induced heat buildup, they help protect sensitive optical components and maintain system stability.
Hot Mirrors vs. Cold Mirrors
- Hot Mirror: Reflects infrared light, transmits visible light
- Cold Mirror: Reflects visible light, transmits infrared light
This makes Hot Mirrors ideal for applications where temperature control and optical efficiency are essential.
Spectrum Transmission Curves
If standard Hot Mirror specifications do not meet your system requirements, SOT provides custom coating designs, allowing optimization of cut-on / cut-off wavelengths, reflection and transmission bands, and substrate material and thickness.

Coating Quality & Reliability Tests
All Hot Mirrors comply with MIL-C-675C and CCC-C-440 standards:
- Adhesion Test: No peeling or blistering after repeated tape removal
- Temperature Cycling: Stable from −62 °C to +71 °C
- Abrasion Resistance: No coating damage after 25 cycles at 1.0 lb force
- Humidity Resistance: No defects after 24 hours at 95–100% RH
- Solvent & Cleaning Resistance: Stable after acetone and alcohol exposure
- Salt Spray Test: No corrosion after 100 hours in 5% salt environment
