905nm bandpass filter (near-infrared region): for TOF and LiDAR

Optical thin-film filters are important optical components designed to transmit and reflect light at specific wavelengths. Optical filters have the troublesome characteristic of "angle dependence," where the transmission and reflection properties change depending on the observation angle and the angle of incidence. This property can be both an advantage and a challenge depending on the usage conditions of the filter. In this article, we will explain in detail the reasons for the angle dependence of optical thin-film filters and its effects, as well as practical considerations and countermeasures. 1. Basics of optical thin-film filters and angle dependence 2. What is angle dependence? 3. Effects of angle dependence and application examples 4. Countermeasures and design considerations for angle dependence A message to designers - from a film manufacturing company For more details, please visit our website.

"We will provide a thorough explanation of infrared windows!" has been added to the technical trend keywords. Optical windows used in the far infrared region (8-14μm) for infrared sensors, thermography, CO₂ lasers, and NDIR gas analysis require a balance of transmittance, environmental resistance, manufacturability, cost, and supply stability. In other words, it is a component that requires multi-axis evaluation of "optical performance × environmental resistance × manufacturability × economic viability × procurement capability," and selecting the optimal material according to the application influences the product's performance, reliability, and cost competitiveness. 1. The technical importance of far infrared windows 2. Optical properties and selection guidelines for representative far infrared window materials 3. What are the typical applications? 4. Trade friction and material availability: supply risks and trends in domestic production 5. A bridge to stable supply and future markets For more details, please check our company website.

We have added a standard stock lineup for the "bandpass filters using colored glass," which has been frequently inquired about! If you are considering a 900nm bandpass filter, please feel free to utilize it. This product is designed to maintain a consistent transmission rate even when the angle changes, and the waveform remains stable even if the angle is misaligned, thanks to the use of colored glass. ◆ About standard stock items from Adachi Shin Sangyo Co., Ltd. .. - I need a few pieces at different levels for urgent product development and performance testing... - I want to try a rough estimate for now... - I would like to make a slight change in shape for prototyping...

In recent years, with the miniaturization and enhancement of optical devices, there has been a growing demand for the deposition of dielectric multilayers on thin glass substrates and film substrates. However, challenges arise when the film stress generated during deposition causes the substrate to warp or the film to curl. Such deformations significantly impact product performance and processing accuracy, necessitating solutions. 【1】Challenges and causes of warping and curling due to film stress 【2】Innovations in deposition fixtures to suppress warping and their benefits 【3】The importance of controlling film stress through optimization of deposition conditions and case studies 【4】Support for cutting processes on thin substrates - Scribe & Dicing Summary For more details, please visit our company website.
