General Description:

The Total Reflector is a critical component used in various laser systems, primarily serving as a back or folding mirror. These mirrors play a crucial role in redirecting laser beams within resonant cavities or transferring them outside the laser apparatus. By incorporating advanced materials such as silicon, copper, and fused silica, these reflectors offer exceptional durability, thermal stability, and thermal conductivity. They are engineered to support high-powered laser systems and are vital for applications requiring precise beam management, such as laser engraving, cutting, and marking. Total reflectors ensure high reflection efficiency, maintaining the intensity and quality of the laser beam throughout its journey.

Spectrum Transmission Curves:

The Total Reflector offers excellent reflection across a broad spectrum, with the typical materials—such as silicon and fused silica—providing reflectivity values of over 99.4% at wavelengths of 10.6 µm (for silicon) and 1064 nm (for fused silica). This high reflectivity ensures minimal energy loss and maximum performance in laser systems.

Coating Quality:

• Adhesion Test: Compliant with MIL-C-675C military standards. The adhesion procedure involves applying tape that meets LT-90 specifications to the film layer, followed by three vertical removals. No blistering or peeling is observed.
• Temperature Test: Test pieces are exposed to temperatures ranging from -62±1℃ to 71±1℃. The adhesion test is repeated after two hours of room temperature exposure, confirming no film detachment.
• Abrasion Resistance Test: In compliance with MIL-C-675C and CCC-C-440 standards, gauze tests apply 1.0 lbs (0.45 kg) of force to the film 25 times, ensuring the film remains undamaged.
• Humidity Test: The film is placed in a chamber with 49±2℃ and 95-100% humidity for 24 hours. After testing, no defects such as peeling or scratches are found.
• Solvent and Cleaning Testing: Following MIL-C-675C specifications, test pieces are exposed to acetone and alcohol for 10 minutes each, showing no signs of peeling or scratches post-cleaning.
• Salt Spray Test: No signs of damage are seen after 100 hours in a 35°C environment with a 5% saltwater concentration.
