1. Precision polishing and molding Domestic production of single-piece aspheric lenses generally uses grinding and polishing at the same time. As technology advances, accuracy becomes higher and higher. Most importantly, the precision polishing of aspheric lenses from China is computer controlled and automatically adjusted to achieve parameter optimization. Aspherical lenses from China. Magnetorheological finish is used …
Optical bandpass filters are specialized components in the field of photonics, designed to transmit light within a specific wavelength range while blocking light outside this range. These filters are pivotal in applications where precise wavelength selection is critical, such as in spectroscopy, laser line separation, or fluorescence microscopy. At their core, optical bandpass filters …
This section aims to provide a foundational understanding of plate beamsplitters. By exploring their fundamental aspects, types, operational principles, material composition, and how they compare with cube beamsplitters, we establish a comprehensive baseline knowledge necessary for professionals in the field. Plate beamsplitter is an optical device that divides an incident beam of light …
Optical coating is one of the most important specification for optical components, they are used to enhance the transmission, reflection, or polarization properties of an optical component. The general coating include Anti-reflective coating (AR coating), High reflective coating (HR coating), Partial reflective coating(PF coating), Polariztion Beamsplitter coating, Non-polariztion beamsplitter coating. MOK Optics has strong capability …
Metalllic mirror coating is appied to the situation where a consistent high reflection on a wide spectral range is needed. Their reflecatance is lower than dielectric high reflection coating. But their spectrum can cover near-UV, visible and near-IR. Dielectric coating is typically applied on the layer of metallic coating to prevent metallic coating from oxidization. …
ISO 10110 is a 13-part standard describing the preparation of drawings for optical components and systems. Each part covers a different aspect of the optical drawing. Part Title Indication 1 General N/A 2 Material imperfections – Stress birefringence 0/ 3 Material imperfections – Bubbles and Inclusions 1/ 4 Material Imperfections – Inhomogeneity and …
Surface Flatness, also called Surface form deviation, is one of the most important specification of optical components. it is the standard deviation of an optical system from its ideal form. They are indicated on the drawing by 3/A(B/C). A is the maximum spherical sag error from test plate. A dash can be substituted for A …

Lidar systems use optical filters to selectively allow specific wavelengths of light to pass through while blocking unwanted wavelengths. These filters are crucial in Lidar systems as they help to eliminate background noise and interference from other light sources. There are different types of optical filters that can be used in laser …
Laser beam expander is a lens assembly which can change the diameter and divergence angle of laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only by adjusting the beam expander to make the laser beam become collimated (parallel) beam, can the focus lens be used to …
