How do you clean a ZnSe lens?

How do you clean a ZnSe lens?

Wet the cotton tip with solvent. Gently wipe the surface with the cotton tip but do not scrub. Repeat as necessary using fresh Q-tips and to finally remove any solvent marks. Use this method with any of the solvents or water/vinegar but finish with a clean Q-tip using acetone.

What is a germanium lens?

Germanium lenses are optical lenses made of polished germanium. These lenses are rugged and resistant to corrosion, and are ideal for harsh environments and applications where there is constant exposure to the elements.

What are CO2 laser lenses made of?

zinc selenide
CO2 laser optics are fabricated from special infrared materials that transmit at the 10.6 micron region: zinc selenide (ZnSe), germanium (Ge), galium arsenide (GaAs) and silicon (Si).

Is zinc selenide toxic?

Toxic by ingestion and inhalation with a danger of cumulative effects. Liberates highly toxic hydrogen selenide in contact with gastric juices. Dermatitis may result from prolonged contact. Particular care must be exercised when machining and creating dust or particles.

How do you clean AR coated glasses?

How to Clean an Anti-Reflective Coated Substrate

  1. In a small clean glass or plastic container mix 1 part isopropyl alcohol to 3 parts clean distilled water.
  2. Use this solution to wet the entire coated surface.
  3. With a soft cotton or microfiber cloth wipe the coated surface dry.

Why is germanium used for for lenses?

Germanium oxide has a high index of refraction, meaning light travels through it more slowly. This gives it applications in wide angle lenses for cameras and microscope lenses.

What is IR lens?

IR Lenses are optical lenses that use specific substrates or anti-reflection coatings to maximize performance for applications operating above 700nm including thermal imaging, FLIR, or spectroscopy. The infrared spectrum refers to 700 – 16000nm wavelengths.

How many categories are there of CO2 lens?

Which focus lenses work best on which types of projects? BesCutter CO2 laser systems are typically equipped with one standard 2.5” focal lens for all the CO2 systems manufactured, but it can change depending on the application. The most common laser lenses are 1.5”, 2”, 2.5” and 4”.

What does a CO2 laser do?

Carbon dioxide lasers can precisely remove thin layers of skin with minimal damage to the surrounding structures. These lasers treat sun damage, wrinkles, scars, warts, birthmarks and other skin conditions.

Is ZnSe a semiconductor?

Zinc selenide (ZnSe), is a light yellow binary solid compound. It is an intrinsic semiconductor with a band gap of about 2.82 eV at 25 °C. ZnSe rarely occurs in nature. It is found in the mineral stilleite named after Hans Stille.

What is ZnSe used for in optical materials?

ZnSe is used widely for IR components, windows and lenses, and for spectroscopic ATR prisms. Zinc Selenide is one of the materials of choice for CO 2 laser optics operating at 10.6 microns. ♦ Zinc Selenide IR Transmission data table ©2019.

What is Zn selenide lens?

Zinc Selenide (ZnSe) Lenses Zinc selenide (ZnSe) is the most popular material for infrared applications. Due to a very wide transmission range covering 0.6-22 µm chemical vapor deposition grown ZnSe as a high optical quality material is used to manufacture optical components. from 138 $

What is ZnSe plano-convex coating?

Thorlabs’ Ø1/2″ and Ø1″ Zinc Selenide (ZnSe) Plano-Convex Lenses are available with a broadband antireflection (AR) coating optimized for the 7 µm to 12 μm spectral range deposited on both surfaces.

What does ZnSe stand for?

Zinc Selenide (ZnSe) Zinc Selenide is microcrystalline in structure, the grain size being controlled to produce maximum strength. Single crystal ZnSe is available, but is not common but has been reported as having lower absorption and thus more effective for CO 2 optics. Zinc Selenide oxidizes significantly at 300°C,…
