Applicable not only to glass substrates but also to polyimide resin and device end faces.
We provide filters with low loss, flat transmission characteristics, and steeper rise times using our unique plasma ion process, ensuring high quality and reliability. We can accommodate your requirements regarding center wavelength, separation wavelength, branching ratio, incident angle, and more.
Filters and mirrors for liquid crystal projectors, such as UV-IR cut filters and polarization conversion elements.
I will explain the roles of each filter and mirror used in liquid crystal projectors.
Good performance, good durability, good cost.
High performance used for cutting-edge research applications. A reassuring 10-year quality guarantee. Achieving prices comparable to conventional soft coat filters through mass production. 【Features】 ○ High performance ○ High durability ○ Low price For more details, please contact us or download the catalog.
We offer high-performance sputtering hard coat filters and mirrors at low prices.
The sputtering hard coat prevents scattering, absorption, and reflection losses, making it possible to produce filters with the highest standards of high transmittance, wavelength accuracy, steep cut-on and cut-off, and excellent S/N ratio. Additionally, it comes with an exceptional 10-year warranty for optical components. The variation between manufacturing lots is extremely small, allowing for stable supply according to the planned delivery schedule. 【Features】 ○ OEM-oriented and low price → High-performance sputtering hard coat filters and mirrors can be offered at prices comparable to conventional soft coat filters. ○ High performance ○ Optical characteristics: high transmittance, wavelength accuracy, steep cut-on and cut-off, excellent S/N ratio ○ Extremely small variation between manufacturing lots, allowing for stable supply according to the planned delivery schedule ○ High durability: reassuring 10-year warranty *For more details, please contact us or download the catalog to view.
I will introduce representative examples regarding wavelength and structure.
The optical pickup uses a 790nm laser for CD recording and playback, and a 650nm laser for DVD recording and playback. The light emitted from each laser source is separated and combined by being transmitted and reflected according to polarization components through filters and mirrors, and is directed to the disk or detector PD.
Optical components that control wavelength, bandwidth, color, and polarization.
The following are representative products. Generally, there are various types such as "dichroic filters," "short pass filters," "color separation filters," and "cold mirrors," and our company can accommodate almost all of them. ◎ They are used in a wide range of applications, including lighting optical systems, projection optical systems, image processing, and cutting-edge research. ◎ Please consult us about the performance and applications you wish to achieve. We will propose the optimal products based on your application/wavelength. ◎ We offer various types, including filter types, mirror types, and prism types. ◎ We can provide design proposals that also consider the effects of polarization and other factors.
