It is a special anti-reflective coating (AR coat) that can have peaks at multiple wavelengths. It is a filter that can be optimally designed for various optical devices.
【1】Are you facing any of these issues? ◆Is it possible to prevent reflection by matching the wavelength of CDs and DVDs? ◆Is there a way to improve visibility and achieve clear image quality? ◆Can we design and deposit custom solutions? ◆I want to increase light output to contribute to energy savings. ◆Can we design an anti-reflective coating (AR) that considers the angle of incidence? 【2】Features of Adachi New Industry's dual-wavelength AR (anti-reflective coating) 1) It is compatible with two wavelengths for CD (780nm) and DVD (650nm). We also offer custom designs that accommodate both DVD (650nm) and Blu-ray/HD-DVD (405nm). 2) It prevents light reflection from both sides of the substrate (thereby improving transmittance). Because it minimizes light loss, clear images can be obtained even in complex optical systems with long optical paths without degrading the incident light. 3) It can accommodate a variety of substrates, including glass and resin films. However, since our process is batch (sheet-type), the maximum size is □200mm.

basic information
◆Design and customization are possible for the desired wavelength range We can design and coat according to the wavelength range requested by the customer. Please provide the wavelength range, transmittance, reflectance, and incident angle, as these are all important factors in the design. If any of this information is incorrect, it may affect performance, so we will conduct a thorough hearing. ◆Component support is also available We can handle everything from substrate procurement to coating. It is also possible to cut to any shape and ship as components. However, we will need detailed drawings. ◆Measuring instruments We will always attach a measurement chart upon shipment, so please rest assured. ◆Cleanroom compliance The working environment is maintained in a cleanroom with the necessary cleanliness for each process from coating to inspection, ensuring a thorough system against minor film defects (such as foreign substances in the film). ◆Safety and security No harmful substances to the human body are used. We can provide data for various environmental surveys (such as Chemsherpa).
