Request InfoLightPath Technologies Inc.ORLANDO, Fla., Nov. 10, 2021 — LightPath Technologies Inc. has announced freeform optics designed for the augmented and virtual reality markets. Freeform optics involve lenses with surface shapes that lack certain symmetrical attributes to provide improved aperture, field of view, and miniaturization. More complex surface profiles allow beam shaping, and many optical systems can be miniaturized while reducing the number of elements to produce optical systems that are small, light, and yield high performance. Applications include augmented and virtual reality, IR and military optical systems, and 3D imaging and...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra March 2022 IssueMotorized LensesThe LensConnect series of motorized lenses from Computar is enables power supply and control through USB connection.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookPassive Athermalization: Maintaining Optical Performance Over Temperature: An optical system is athermalized if its critical performance parameters (such as modulation transfer function, back focal length and effective focal length, etc.) do not change appreciably over the operating temperature range.For rotationally symmetric optical systems, either the lens or the detector moves along the optical axis to maintain optical performance. If the compensating axial motion is accomplished without the...Photonics HandbookExcimer Optics: High Power Demands High Reliability: The excimer laser’s shift to commercial applications has created a demand for higher power levels and increased reliability from the laser itself, thus creating a greater demand for industrialized optics to control, redirect, reshape, and focus the intense UV radiation produced.The first high-reflectance mirror coatings for the UV and vacuum UV (VUV) were of the Al + MgF2 type produced in the late 1950s. Coatings of this design are still used today for multigas cavity...WHITEPAPERSPhotonics.com 10/25/2021New Telecentric Optics with Liquid Lenses TechnologyAnyone familiar with telecentric optics knows very well that the depth of field can be a problem when using high-magnification lenses.
