Optical Componets Knowledge

Here we’d like to inform that our company will back to work on February 9th,  because affected by a novel coronavirus, our government announced all enterprises will remain closed till February 9. China is determined and capable of winning the battle against the coronavirus. We all take it seriously and follow the government’s instructions to contain the spread of the virus. The atmosphere around remains optimistic to some extent. The epidemic will be eventually controlled and killed. I believe, China’s speed, scale and efficiency of response is rarely seen in the world. Thank you for your understanding!

Ball lenses are great optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. Ball lenses are manufactured from a single substrate of glass and can focus or collimate light, depending upon the geometry of the input source. Half-ball lenses are also common and can be interchanged with full ball lenses if the physical constraints of an application require a more compact design. VY Optics offers a variety of ball lenses and half ball lens in a range of substrates for performance in the ultraviolet to the NIR. Material options include: quartz (260-2500nm), sapphire (0.17–5.5 μm), ruby (250 nm to NIR), BK7 (or equivalent) (250–2500 nm), UV-grade fused silica (170–2500 nm), as…

Researchers at the Physical Research Laboratory at Gujarat University have developed a compact and ultrafast high-power yellow laser. The tunable laser shows excellent beam quality, helping fill a need for a practical yellow light source emitting ultrafast light pulses. While studies have shown lasers in the yellow spectral range are useful for certain medical treatments, their wavelengths are typically created using bulky and inefficient copper vapor lasers, dye lasers, and optical parametric oscillators. These sources have been successful in their use for various applications but suffer from drawbacks that can include low average power, the lack of an optimal spatial beam profile, limited or no wavelength tunability, and broad output pulses. We demonstrate a robust, high-power, ultrafast, tunable yellow radiation in a rather simple experimental configuration,” said Anirban Ghosh, a…

ZnSe is a light yellow binary solid compound that is rarely occurs in nature. It can be made in hexagonal and cubic crystal structures. Zinc selenide is used as a blue light source in light-emitting diodes and diode lasers. It is also used as infrared laser gain medium and as an infrared optical material. ZnSe activated with tellurium is used in x-ray and gamma ray detectrs as a scintillator. Zinc Selenide (ZnSe) Optical Components are Optical Components designed for the Infrared (IR) spectrum. Zinc Selenide (ZnSe) is used in a range of Optical Components, including Optical Windows or Optical Lenses, for applications including thermal imaging or FLIR. Zinc Selenide (ZnSe) Optical Components are ideal for integration into CO2 laser systems because of its low absorption coefficient combined with its high…

* What is Nd:YAG Laser?   Nd:YAG laser is the short form used for Neodymium-doped Yttrium Aluminium Garnet. It is a solid state and 4 level system as it consists of 4 energy levels. Nd ion is rare earth metal and it is doped with solid state host crystal like yttrium aluminium garnet (YAG – Y3Al5O12) to form Nd:YAG laser. Due to doping, yttrium ions get replaced by the Nd3+ ions. Also, the doping concentration is around 0.725% by weight. Its working principle is such that when optical pumping is provided to the device. Then the Nd ions get raised to higher energy levels and their transition produces a laser beam. This laser generally emits light of wavelength of nearly 1.064 μm. * Construction of Nd:YAG laser Nd:YAG laser is basically categorized…

The prism is a polyhedron made of a transparent material such as glass or crystal. It is widely used in optical instruments. Prisms can be divided into several types according to their nature and use. For example, in a spectroscopic instrument, a composite lens is decomposed into a “dispersion prism” of a spectrum, and an equilateral prism is more commonly used; in an instrument such as a periscope or a binocular, the direction of light is changed, thereby adjusting the imaging position thereof. Reflective prisms, generally using right-angle prisms. VY Optoelectronics Co.,Ltd. offers a wide range of Optical Prisms in a variety of designs, substrates, or coating options. Designs include Right Angle, Amici, Penta, Schmidt, Wedge, Anamorphic, Equilateral, Dove, or Rhomboid prisms, in addition to Corner Cube Retroreflectors or Light…

CCTV lens is usual in daily life, here we’d like to share how to choose a suitable CCTV lens for your camera. Firstly, to find out what kind of mount for your CCTV lens. C, CS or board, it depends on the camera or sensor that a lens works with, so to check your camera o sensor firstly. Board lens thread: M12x0.5, C or CS mount lens thread: 1-1/32”. For the second, choose correct angle of lens. It is important to understand the angle of the lens, the angle of view depends on the focal length. • The larger the number focal, the narrower the angle of view. • The sensor of camera (h×v ): 1” sensor: 9.6mmx12.8mm, 2/3” sensor: 6.6mmx8.8mm 1/2” sensor: 4.8mm X 6.4mm, 1/3” sensor: 3.6mm x…
