2. General Description

Shape Optics Technologies Pte Ltd (SOT) provides high-performance Laser Welding and Cutting Filters, ideal for use in precision laser systems. These filters are specifically designed for applications in laser welding, cutting, and other industrial laser processing operations.

The filters are crafted from high-purity quartz, offering excellent optical performance under extreme temperatures and high-power conditions. With precise wavelength transmission, they allow specific laser wavelengths, such as 355nm and 1064nm, to pass through with minimal loss, ensuring maximum energy is delivered during the welding or cutting process.

SOT’s filters also provide outstanding durability, thanks to a protective coating that enhances resistance to abrasion and environmental damage. Whether used in automated manufacturing systems or high-precision surgical laser systems, these filters ensure the laser energy is efficiently transmitted while blocking out unwanted wavelengths.

SOT offers customizable options, making it easy for customers to tailor these filters to suit their specific needs, ensuring the best possible performance in each unique application.

3. Spectrum Transmission Curves

The Laser Welding and Cutting Filters feature specific spectrum transmission curves, ensuring that only the required wavelengths are transmitted. These curves are tailored to the 355nm and 1064nm ranges, optimizing the system’s energy efficiency and effectiveness. For non-standard applications, SOT offers customized services to provide the ideal wavelength transmission characteristics for each system.

4. Coating Quality

The Laser Welding and Cutting Filters undergo rigorous testing to meet industry standards for optical performance and durability:

• Adhesion Test: Filters meet MIL-C-675C military standards. Adhesion testing involves applying a tape with LT-90 specifications, followed by vertical removal after three repetitions, with no blistering or peeling observed.
• Temperature Test: Filters withstand temperatures between -62±1℃ and 71±1℃ without film detachment, even after two hours of exposure at room temperature.
• Abrasion Resistance Test: Conforms to MIL-C-675C and CCC-C-440 standards, demonstrating durability against abrasion when tested with a gauze tester.
• Humidity Test: The filters perform excellently under MIL-C-675C criteria, showing no damage or peeling after exposure to 95%-100% humidity for 24 hours.
• Solvent and Cleaning Testing: Filters retain their integrity after being exposed to acetone and alcohol for at least 10 minutes each, followed by air drying and cleaning.
• Salt Spray Test: After 100 hours of exposure to a 35°C environment with 5% saltwater, the filters show no signs of degradation.
