Product Description

We are manufacturers of Precision optics & Optical Components viz. Windows, Prisms, Lens, Optical coating Mirrors, Beam splitters, Filters, Band pass, Reticles, Optical flats, Cylindrical lens, Prism cement, etc. We are partners to our customers, providing high-quality solutions meeting demands. The high quality of our products and services, and the satisfaction of our customers are our ultimate objectives. These objectives are based on the benchmark of compliance with the statutory and official regulations, where different requirements exist depending on the market. We are constantly developing our products, technologies and services in the interests of our customers and partners. In doing so, we comply with international standards in accordance with ISO 9001 for quality management. Please find below a short description of our PHYO BK7/Fused Silica /ZNSE/ Sapphire Optical Protective Windows

Optical Window: Optically flat, double sides parallel polishing of the optical glass into a relatively high precision of the surface. Mostly it is used for the testing or assembly equipment's in order to allow light get into the testing machine or the instruments. PHYO Optics provide many different type of windows using various optical material, like BK7, Fused Silica,Ge, ZnSe, Calcium, Sapphire or MgF. Including Parallel or wedge. Most of them with the AR coating to improve the transmission rate in display from UV to IR light. Some parts can be used in the laser system in a high flatness and surface quality.
Protective windows for high-energy lasers are designed to be used as a safeguard for the more expensive optics inside the laser cutting head. They are placed as the last optics before the work piece.
Installing these means that debris, fumes, and splashes are deposited on the protective windows for high-energy lasers instead of the expensive focusing lenses. Eventually, these consumable windows must be changed once debris starts damaging the dielectric coating. Our protective windows come packed individually for fast replacement.
Our experience has led us to achieve spectacular results with high-power systems. We use high-quality substrate materials and top-quality coatings for our AR coated windows. Our designed and in-house made coatings provide two main benefits:

• They prevent any backscattering and reflections during the processes
• They increase process efficiency by minimizing reflective losses from windows

In general, this allows us to offer items that can withstand power rates exceeding several kW. Some of our most popular protective windows are ready off the shelf. If not, PHYO can prepare AR coated windows according to the needs of your system.
PHYO protective windows are widely used in the optical systems, to protect the inside precision optical systems from dust, water, scratches, damage, etc. They can be customer designed in different size, surface polishing standard, and apply coating. Windows can be round or rectangle, or with R chamfer of angles, with installation steps
UV Fused Silica Windows plate are precision manufactured using UV-grade synthetic fused silica. In addition to superior transmission, the synthetic fused silica of these optical windows exhibits higher thermal properties, exceptional purity,and excellent environmental durability for demanding applications.
