  • More UV intensity at the required frequencies
  • Less heat generated
  • Longer lifespan of the lamps
  • Deeper and more uniform curing
IR Coatings

they allow infrared light to be managed selectively, improving the efficiency of optical systems.

They allow you to:
  • create band-pass filters to reflect or transmit IR
  • increase the efficiency of optical instruments in the infrared range
  • improve the performance of high-power lasers
07 Thermal Management

Heat Filters

Heat Filters

Heat filters, known as "hot mirrors", are designed for precise thermal management, selectively reflecting infrared radiation (heat) and allowing visible light to pass through. This technology is crucial for protecting heat-sensitive materials in high-light-intensity applications.

Main Function
They reflect heat (IR) and transmit visible light, ensuring the protection of optical components and samples.
Advanced Protection
They allow the use of powerful light sources with materials and substrates sensitive to overheating.
Wide Applicability
The coatings are compatible with most optical substrates, offering solutions from ultraviolet to infrared.
