UV lenses are often very expensive and it is difficult for customers to find lenses that meet specific requirements. Alfa Chemistry provides a broad selection of premium custom UV lenses for a range of uses. These lenses have excellent transmission in the UV spectrum (10~400 nm) and are composed of premium materials. By taking into account all design factors, such as specs, budgets, and delivery timelines, we offer optimum UV lens solutions. Alfa Chemistry can use a UV anti-reflective multilayer coating to provide broad spectrum coverage and over 99% transmission per surface.
Our Capabilities
Alfa Chemistry uses a variety of UV materials to create UV lenses that are uniquely yours, such as:
- Calcium fluoride - It can function in vacuum UV and extreme UV down to 130 nm.
- Quartz - It begins transmitting effectively at 260 nm, making it suitable for UV A, B, and C applications.
- UV-grade fused silica - It functions well up to 175 nanometers in the far-UV band and achieves 85% transmission at 185 nanometers.
Custom UV-Grade Biconvex Lenses
We create custom UV-grade biconvex lenses using UV-grade components like fused silica and calcium fluoride. Custom transmission enhancement films can be used to improve performance in deep UV applications.
Custom UV-Grade Curved Moon Lenses
Because UV-grade fused silica performs well in deep UV, we use high-quality custom UV-grade curved moon lenses at 175 nm.
Custom UV-Grade Concave Lenses
In a variety of UV instrumentation applications, custom UV-grade concave lenses can be utilized to correct spherical aberrations brought on by other lenses. Concave lenses are hence excellent for regulating the laser beam. Our line of custom UV concave lenses can be utilized for deep UV applications down to 175 nm and achieve 85% transmission at 185 nm. They have normally manufactured of UV-grade fused silica.
Custom UV-Grade Cylindrical Lenses
UV cylindrical lenses are frequently used to modify a laser beam's profile or to produce lines for single-mode lasers. We provide a variety of custom UV-grade cylindrical lenses that reach 85% transmission at 185 nm while still operating effectively at 175 nm in deep UV applications. These lenses are manufactured of UV-grade fused silica.
Custom UV-Grade Ball and Hemisphere Lenses
We offer a variety of bespoke hemisphere and ball lenses that can be made to order. Custom UV-rated ball lenses can be produced in a range of grades, from Class 3 to Class 25, which is a mid-range grade, to Class 200, which is a commercial-grade grade. Custom UV ball and custom UV hemispherical lenses are most commonly used to couple light into and out of optical fibers.
Custom UV-Grade Plano-Convex Lenses
In UV optical systems, custom UV grade plano-convex lenses are often utilized to concentrate or gather light. We normally provide a whole range of focal lengths between 3 mm and 450 mm in diameter. UV-grade fused silica, an ideal material option for applications in the deep UV spectral range, is utilized to create custom UV-grade plano-convex lenses. UV-grade fused silica is the best material for medical fluorescence applications because of its high chemical purity, superior thermal conductivity, and low fluorescence.
Quality Assurance
Each custom UV lense is carefully tested to all applicable standards using state-of-the-art metering equipment. We inspect and scrutinize every product before it's shipped to customers, so customers can have complete confidence that the optics they order will be the best fit for their application.
Alfa Chemistry is always looking to expand and work with customers to achieve their specifications, so please feel free to contact our technical sales team for more information and guidance on your enquiry.
