Request InfoDeposition Sciences Inc. (DSI)Deposition Sciences Inc. offers durable antireflection (AR)-coated ball lenses in diameters from 200 µm to 10 mm. The IsoSphere lenses are created using a proprietary low-pressure chemical vapor deposition process that provides uniform coating over the entire surface of the sphere. The company’s multilayer coating capability provides dual- and broadband coatings (1310/1550-nm dual band). The dual-band coatings allow one lens to be used for either wavelength. A choice of lens materials, with indices from 1.44 to 2.15 at 1550 nm, minimizes cost and provides freedom in the optical design....See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueMEMS Autofocus ActuatorThe MEMS Autofocus Actuator for Active Athermalization in Embedded Vision Cameras from Sheba Microsystems Inc. was made to be used in automotive, action, drones, machine vision, security and...Photonics Spectra September 2022 IssueDirect Time-of-Flight SensorThe VL53L8 direct Time-of-Flight sensor from STMicroelectronics can be used for smartphones, smart speakers, human-machine interfaces, consumer lidar, augmented reality, and more.
