Narrow Bandpass Filter

Yunlang can provide precision filters for many applications, including bandpass interference filter (band pass filters), Cut off filters, UV bandpass filter, Narrow bandpass filter, ND filter, Negative Filter or Notch filters, dichroic, color substrate. Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries. Custom filters are available for both large manufacturing needs and in prototype volumes.

Sapphire Windows

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm. We can supply professional customized service in time and provide cooperation and support of new product development and technology appliance.

Optical Windows with Hole

An Optical Window is an optically flat. These regular windows are applied to isolate different physical environments while allowing light pass. When selecting windows,please consider materials, transmission, scattering, parallelism and resistance to certain environment. It can be widely used on laser technology, IR detector and imaging technology etc.

Yunlang offers standard and high precision optical glass windows in round ,rectangular, wedge windows and custom shape and size with different optical glasses,Fused Silica, Sapphire, ZnSe, Zns and IR crystal. The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of λ/20. Single layer or multi-layer anti-reflection coatings are available.

Tapered Light Pipe prism

Light pipe homogenizing rods utilize total internal reflection to homogenize non-uniform light sources regardless of their spectral characteristics. TECHSPEC® Tapered Light Pipe Homogenizing Rods are available in both 2X and 3X magnifications. The Numerical Aperture (NA) of the light output is reduced proportionally to the magnification, allowing significant reduction in NA of the output light.

Optical Cube Prism Beamsplitter

Standard Beamsplitter Cube
A Standard Beamsplitter Cube is independent of polarization. The incoming light should be: 45°linearly polarized, circularly polarized or natural light. The outgoing beams are two partially polarized beams of about the equal intensities.
Polarizing Beamsplitter Cube
A polarizing beamsplitter cube consists of two right angle prisms cemented together. The hypotenuse face of one prism is coated with a special multilayer dielectric coating. When circularly polarized or natural light enter the cube vertically, it separated into two linearly polarized beams. The transmitted beam is P-polarized while the reflected beam is S-polarized.
And when a linearly polarized light come in, it similarly divided into two beams. But the energy ratio of the two outgoing beams is depending on the polarization of the incident beam. Polarizing beamsplitter cubes are available for many laser wavelengths and broadband ranges.
Non-Polarizing Beamsplitter Cube
These cubes split the energy with minimal polarization sensitivity. The polarization states are about the same for the entrance and exit beams.
Broadband Non-Polarizing Beamsplitter Cube’s hybrid coating has certain absorption but minimal polarization sensitivity. Due to the metallic nature of the hybrid coating, those cubes are not intended for use with high powerlasers.

Dove Prism

Dove prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of the longest (bottom) face and emerges from the opposite sloped face. Images passing through the prism are flipped, and because only one reflection takes place, the image's handedness is changed to the opposite sense. Dove prisms have an interesting property - when they are rotated along their longitudinal axis, the transmitted image rotates at twice the rate of the prism. It is very important that the application must be used with parallel or collimated beam and the large square reflective surface should be kept very clean. Another application is used as a retroreflector. For this application it performs as a right-angle prism.
Used in Interferometry, Astronomy and Pattern Recognition.

Right Angle Prisms

Right angle prisms are extremely versatile optical components, commonly used as individual prisms and components of optical assemblies.
Right angle prisms are optical elements having at least three polished faces inclined relative to each other at 45-90-45 degrees. They can be used as total internal reflectors, hypotenuse face reflectors, retroreflectors and 90 degrees beam benders.
Various HR or AR coatings are available specified in the Coatings section. Custom fabrication also available: coating, cutting, edging, drilling according to your specification.
Substrate options include N-BK7, H-K9L UV Fused Silica, N-SF11, Calcium Fluoride (CaF2), Germanium (Ge), or Zinc Selenide (ZnSe).
