A bandpass filter that achieves sharp rise and high transmittance in the visible light range (660nm). It is ideal for red laser diodes and LED applications.
Are you having trouble with something like this? - Is it possible to only allow a specific wavelength (633nm) to pass through? - I would like to expand the stop band because light other than the desired wavelength becomes noise. - Can you take into account the range of incident angles? - The shape is special; can it be shipped as a component? Optical bandpass filters are used in various optical applications and are essential for selectively extracting light of specific wavelengths. Passband: An optical bandpass filter allows a specific range of wavelengths to pass through. This range of wavelengths is called the passband and is typically defined by the center wavelength and the wavelength bandwidth. Wavelength selectivity: Optical bandpass filters can have very high wavelength selectivity, emphasizing light of specific wavelengths. This is important in many fields where precise wavelength selectivity is required. A 660nm bandpass filter, which selectively allows light in the specific wavelength range of 660nm to pass through, is commonly used in optical applications. This bandpass filter amplifies or allows light within the wavelength range around 660nm while blocking light of other wavelengths.

basic information
1) Excellent wavelength selectivity and a design that minimizes wavelength shifts. 2) Optimal design for substrates By utilizing the characteristics of the substrate used, we achieve the optimal filter through design. 3) Design and customization possible for desired wavelength ranges We can design and deposit (coat) according to the customer's requested wavelength range. Control in both the transmission range and the stop band, 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. 4) Component support is also possible We can handle everything from substrate procurement to deposition. It is also possible to cut into any shape and ship as components. However, we will need detailed drawings. 5) Measurement equipment: We own FT-IR We will always attach a measurement chart upon shipment, so please rest assured. 6) Cleanroom compliance The working environment maintains the necessary cleanliness from deposition to inspection, and we have a thorough system in place to address minor film defects (such as foreign substances in the film). 7) Safety and peace of mind No harmful substances to the human body are used.
