Mutilayer FillterOptical filters
The highly transparent material of the derivative of metallic oxide is widely used as the material for for optical thin film. The dielectric multilayer is applied by using more than two types of refractive indices. We can provide a wide variety of characteristics. We produce by "vacuum deposition method".
You can use ISUZU's absorbing filter such as ITY430 and ISK150 as a glass substrate. If you use an absorbing filter as a glass substrate, you can easily get better transmissive properties with less layers than using a clear glass such as B270 . Incident angle dependence is also improved by decreasing the number of layers.Hence, we can offer the best optical filter suitable for your specific application.
【Example of product 1】
This graph is simulation data of sharp cut filters when using ITY 430 as a glass substrate. ITY 430 offers UV absorbing function in glass material itself, which cuts UV on a shorter than 420nm and when combined with multi layer film coatings, we can offer sharp cut filters which have 50% point on a longer wavelength side.
【Example of product 2】 This graph is simulation data of IR sharp cut filter when using ISK150 as a glass substrate . ISK150 offer IR absorbing function in glass material itself, which cuts IR on a longer than 1000nm and when combined with multilayer film coatings, we can offer IR sharp cut filter which sharply cuts infrared rays.
