Optical Lenses are visual components designed to focus or deviate light. Optical Lenses are used in a various applications from microscopy to laser processing. These lenses which may comprise of a single or multiple elements are utilized in variety of industries, including life sciences, imaging, industrial, or defence. When light passes through a lens, it is influenced an underlying layer of the lens. UV optics are lenses containing single or multiple elements and designed to operate in ultraviolet spectrum. There is a wide variety of standard UV Lenses available in the market today, including singlet lenses such as PCX or plano-convex lenses, achromatic lenses, or ball lenses. PCX lenses are optical lenses with a positive focal length. These lenses are best-suited for focusing applications that utilize monochromic illumination in an array of industries like robotics, defense, or pharmaceuticals. Now, coming to the silicon optics which is a evolving technology wherein data is transferred among computer chips via optical rays. These optical rays are capable enough to carry more data in less time as compared to electrical conductors. Silicon optical components are utilized in numerous infrared applications, including IR spectroscopy or NIR imaging. The low density of silicon optics is ideal for use in weight-sensitive applications. Silicon optical lenses are available in the variety of sizes or focal lengths. Silicon photonics are highly utilized in computer communication as there the optical links have an extended reach from centimetre to meter. Sapphire is known as the hardest natural substance next to diamond and owing to its extreme hardness, toughness, and high strength it is abest-material choice for high-performance optics. There are many advantages of sapphire optics that out stand it from other optical materials like extreme surface hardness, wide optical transmission band from UV to Mid IR, high electrical resistance, high thermal conductivity for a non-conductor.
Laser diode is a semiconductor device that can directly convert electrical energy into light. The use of laser diodes has radically increased in both commercial and industrial setups. Laser diode’s small size, ruggedness, and of course its optical characteristics have increased its usage. Laser diode optics are apposite for high definition TV (HDTV) development, cable TV transmission, and for medical applications.

Laser mirrors are superior quality mirrors used in laser resonators and other optical setups. There are different standards which should be met by the resonator of a laser which contains mirrors which are low reflection losses or a precise transmission in a certain wavelength range, high optical quality of the surface, and good resistance against high optical intensities. Dielectric mirrors built on multi layer structures are used as laser mirrors. Additionally, Laser mirrors can also be used to reflect light outside the laser resonator. Surface quality plays a significant role for most laser mirrors which is primarily used to avoid beam distortion. Laser mirrors should be highly reflecting for better laser wavelength. Now, let’s discuss and trace the difference between hot and Cold mirrors. A Hot mirror is a specific dielectric mirror which is often used to protect optical systems by reflecting infrared light back into a light source, while allowing visible light to pass. On the other hand, cold mirrors reflect the entire visible light spectrum while efficiently transmitting infrared wavelengths. Both types of mirrors can be designed to be inserted into the optical system at an incidence angle ranging 0 to 45 degrees. Hot mirrors are helpful in applications where the accumulation of waste heat can damage components. Both mirrors can be employed as dichroic beam splitters with laser systems to reflect visible light wavelengths.
IPL Light guide plays a key role in cosmetic laser and other laser applications. IPL is commonly a laser application used for removing unwanted hair from the body. These applications use varied range of wavelengths to target different chromospheres- the target molecules found in the skin.
In the recent years, there has been increased use of light-based technologies in dermatology. Laser and intense pulse lights are used to tray a variety of cutaneous conditions, including vascular and pigmented lesions, tattoos, scars etc. These procedures are becoming popular worldwide as they proven to be successful in treatment of various skin conditions. This has led to increase in the demand for existing products, new innovations and clinical applications. Most manufacturers offer custom IPL light guide in a wide array of materials and coatings to suit different waveband requirements. For instance, custom BK 7 or equivalent light guides provide high internal reflection to minimize the loss of transmitted light and is considered as an excellent choice for IPL applications Custom UV fused silica light guides is also an excellent alternative to BK 7 or equivalent for pigmentation treatment. Custom sapphire light guides is also commonly used as it is an extremely hard material that offers increased durability and great resistance to damage. |
