2. General Description
Shape Optics Technologies Pte Ltd (SOT) provides high-quality optical plastic coatings designed for a range of applications including biomedical imaging, optical instruments, and digital technologies. These coatings are applied to acrylic, polycarbonate, and other optical materials, offering precise control over optical transmission and reflection properties. Our optical coatings are tailored for use in devices requiring high light transmittance and superior durability. Custom designs ensure that the coatings meet specific requirements, whether for UV protection, visible light filtering, or infrared transmission. These coatings can be integrated into various optical elements such as lenses, filters, and protective windows, contributing to improved device performance and longevity.
3. Spectrum Transmission Curves
SOT offers a wide range of standard and custom coatings. The standard components exhibit high optical transmittance with minimal loss over a broad wavelength spectrum (400-1100 nm). Custom coatings can be designed upon request for specific wavelengths or more complex requirements, such as narrow or broad bandpass filters, with specific transmission percentages.
4. Coating Quality
- Adhesion Test: In compliance with MIL-C-675C military standards, an adhesion test is conducted using tape that meets LT-90 specifications. The tape is applied to the lens film layer, affixed fully, and then removed vertically. This process is performed three times, showing no blistering or peeling.
- Temperature Test: As per MIL-C-675C specifications, the coating undergoes temperature exposure between -62±1℃ and 71±1℃. After two hours at room temperature (16℃~32℃), the adhesion is tested again to confirm no film detachment.
- Abrasion Resistance Test: In line with MIL-C-675C and CCC-C-440 standards, this test applies a force of 1.0 lbs (0.45 kg) using a gauze tester, which is repeated 25 times with gauze widths of 1/4 inch (6.4 mm) and 3/8 inch (9.5 mm), ensuring no damage to the surface.
- Humidity Test: The film is placed in a controlled chamber at 49±2℃ and 95-100% humidity for 24 hours, showing no peeling or surface defects.
- Solvent and Cleaning Testing: Compliant with MIL-C-675C standards, the film is exposed to acetone and alcohol for at least 10 minutes each, followed by cleaning with a cotton cloth soaked in alcohol. The surface is unaffected by this process.
- Salt Spray Test: After being exposed to a 5% saltwater concentration in a 35°C environment for 100 hours, the film shows no degradation.
