2. General Description
Shape Optics Technologies Pte Ltd (SOT) offers high-performance Dielectric HR Mirrors designed to provide excellent reflectivity and durability. These mirrors are constructed using a dielectric film on a substrate, such as JGS1 or K9 optical glass. The dielectric coatings enhance the reflective properties, ensuring that these mirrors deliver consistently high reflectivity over a broad range of wavelengths, from 200 nm to 2000 nm. The mirrors are specifically designed for high-power applications, with a high damage threshold that ensures reliable performance under intense laser exposure.
The dielectric HR mirrors are available in different sizes and angles of incidence (AOI), making them suitable for a variety of optical systems, including stage engineering laser high mirrors, high-precision optical instruments, and digital microscopes. These mirrors are also essential components in high-power laser reflection systems, galvo laser motors, laser barcode scanners, and projector optical engines.
SOT’s dielectric HR mirrors are crafted with strict quality control standards to meet the specific needs of diverse industries. Customization options for size, reflectivity, and other specifications are available upon request.

If the standard components do not meet your specific requirements, SOT offers customized solutions. Upon request, we can provide mirrors tailored to your exact wavelength and reflectivity needs.
4. Coating Quality
- Adhesion Test: The coating meets MIL-C-675C military standards for adhesion. The adhesion test involved applying a tape that meets LT-90 specifications to the lens film layer. The tape was applied fully and removed vertically three times, showing no blistering or peeling of the film.
- Temperature Test: In accordance with MIL-C-675C standards, test pieces are subjected to temperatures from -62±1°C to 71±1°C. After maintaining the pieces at room temperature (16°C-32°C) for two hours, the adhesion test confirms no detachment of the coating.
- Abrasion Resistance Test: The abrasion resistance test follows MIL-C-675C and CCC-C-440 standards, using a gauze tester to apply a minimum force of 1.0 lbs (0.45 kg) for 25 cycles with no damage to the surface.
- Humidity Test: Under MIL-C-675C criteria, the test pieces are placed in a controlled temperature and humidity chamber set at 49±2°C and 95%-100% humidity for 24 hours. The coating remains intact, with no visible peeling or defects.
- Solvent and Cleaning Test: Following MIL-C-675C specifications, test pieces are exposed to acetone and alcohol at room temperature for 10 minutes. After air drying and cleaning with a cotton cloth soaked in alcohol, no peeling or scratching is observed on the surface.
- Salt Spray Test: After 100 hours in a 35°C environment with a 5% saltwater concentration, no damage to the coating is observed, demonstrating excellent resistance to corrosion.
