How to Specify Surface Figure and Wavefront Distortion for Multi-layer Optical Filters
Optical filters are used in many applications and the surface figure and wavefront distortion requirements of filters are dependent on where and how they are used. Whereas band-pass or clean-up functionality may only require control of the transmitted wavefront, dichroic beam-steering/splitting filters or wavelength selective mirrors likely require specification of both the transmitted and reflected beams. If filters are only used in sensing applications with very tolerant detector geometries, there may be no need, in practice, to put any constraints on the surface figure or wavefront distortion. It is important to understand where, when, how, and how much to specify wavefront distortion to ensure that functional requirements are guaranteed while unnecessary and costly constraints are avoided.
LiDAR and Optical Filters for Autonomous Vehicles
“What’s a ‘steering wheel’?” At the present time this would be a very strange question to hear asked from anyone who has driven, ridden in, or even seen a car but in a couple of decades this may not seem so unusual. The evolution of increasingly affordable and capable sensing and imaging systems combined with the desire to create safer, more efficient transportation systems is driving the development of autonomous vehicles (pun intended). LiDAR is a key technology that will eventually help carry this growth through to “Level 5” autonomy : no steering wheels, no brake pedals, no human intervention in driving.
The Right Filter for MWIR Equipment
Utilization of mid-wavelength, also called midwave, infrared (MWIR) light is critical in many areas, including thermal monitoring of equipment and homes; gas absorption; military enhanced-vision systems for imaging vehicles, people, and terrain; and environmental monitoring of gases. Even diagnosis of pregnancy in dairy cows, among other applications, can productively use infrared in the MWIR range.
フィルターの仕様の指定方法
必要な光学フィルターの仕様は、フィルターのアプリケーションと使用方法によって変わってきます。 一般的に、典型的なフィルター光学仕様には、光を反射・透過する波長範囲、入射角調整範囲、フィルターの開口径、非正規入射角での偏光状態、光のコヒーレンス（レーザーまたは白色光）、光学ビームサイズと光の円錐角、希望の基板材料（寸法を含む）、および入射光媒体（空気またはガラス）などが含まれます。 さらに、動作温度範囲やフィルターの周囲環境などの物理的仕様も指定する必要があります。 AOI および CHA: 入射角（Angle of...Optical Interconnects for Data Centers- Lighting the Cloud

“Measurement is the first step that leads to control and eventually to improvement. If you can’t measure something, you can’t understand it. If you can’t understand it, you can’t control it. If you can’t control it, you can’t improve it.”
