Craftsman's Point: Achieved optical properties with a periodically varying refractive index. Application: Expected applications in notable fields such as Raman spectroscopy.
We will achieve optical characteristics that have not been realized before by periodically changing the refractive index. Conventional optical filters (optical thin films) consist of alternating layers of high-refractive-index and low-refractive-index films, which exhibit specific optical properties. In contrast, notch filters (band-stop filters) are deposition products designed to periodically change the refractive index in the thickness direction. A characteristic feature is that no optically unnecessary ripple occurs outside the stopband. We can achieve optical characteristics that were not possible with previous optical thin film processing. (Do you have such challenges?) ■ Is it possible to reflect only around the wavelength of 532nm? ■ I would like the unnecessary parts to be unable to transmit optically. ■ Notch filter? Band-stop filter? Rugate filter? ■ I have heard that the measurement difficulty after deposition is high; can you accommodate this?

basic information
1) Features: ■ Excellent wavelength selectivity ■ Sharp edge filter It has the characteristic of transmitting or blocking light with a steep change. 2) Design and customization available for the desired wavelength range We can design and coat according to the customer's requested wavelength range. Control in both the transmission and blocking regions, as well as the angle of incidence, are important factors. We will design according to the characteristics of the substrate and the customer's requirements, so please provide the type of substrate and wavelength range when inquiring. 3) Component support is also possible We can handle everything from substrate procurement to coating. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 4) Measurement instruments We will always attach a measurement chart upon shipment, so please rest assured. 5) Cleanroom compliance The working environment maintains the necessary cleanliness for each stage from coating to inspection, and we have a thorough system in place to address minor film defects (such as foreign substances in the film).
Price information
