Sapphire Lenses

 Sapphire Lenses

 

Sapphire is the best medium for spherical lenses that require a broad spectrum of light transmission and high optical clarity, especially in demanding applications such as laser system or working under harsh environmental conditions. With its excellent hardness, high thermal conductivity and resistance to chemical acids and alkalis, sapphire’s physical property is hard to machine, also requires unique polishing techniques.

 

At Hyperion Optics, our technicians are able to deliver excellent accuracy exactly customers ask for, no matter the finished products are used through infrared wavelength or within UV range, our sapphire products suit following applications:

 

Endoscopes & medical optical applications

Infrared (IR) sapphire glass optics for laser systems

Sapphire optics for LEDs & lighting applications

Sapphire lenses, reflectors & holders for fiber optics applications

Sapphire light pipes & light guides for IR transmission

 

Our precision sapphire lenses are widely used in imaging optics, chemical and erosion resistance front surface optics as well as focusing lenses.

Magnesium Fluoride Lenses

 CVD magnesium fluoride (MgF2-CVD) has good mechanical properties, chemical stability, impact resistance, great anti thermal fluctuations and radiation. While it has excellent transmission from 0.11 to 9 um, suitable for optical lenses, wedge, and window manufacturing. MgF2 coating is also considered as durable material in deep UV and LWIR applications.

 

Hyperion Optics offers custom parameter MgF2 lenses; we strictly control the alignment of C-Axis to avoid birefringence effects during usage. Please talk to our technicians of further information.

Germanium Lenses

 Ge Lenses  

In the range of 2-12 μm, germanium is the most commonly used material for the production of spherical lenses and germanium ir windows for high efficiency infrared in the imaging system. Germanium has a high refractive index (about 4.0 through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems.

 

Germanium optical performance is severely affected by temperature; the transmission rate decreases with the increase of temperature, most applications with Germanium elements involved can only be applied below 100 degrees Celsius. Designers also need to pay attention for certain weight constraints in system design with a density of germanium (5.33 g/cm3). Germanium is mainly used in the thermal imaging system and infrared (FLIR) field.

 

It is critical that the surface of the material has a promising finish and good transmittance. Hyperion Optics provides 40-20 surface quality Ge lenses as factory standard products, with up to 1/4 lambda in surface accuracy. Our outstanding CNC lathe capability has leveraged our machining efficiency to meet rapid delivery. Ge aspheric infrared lenses stand up well to harsh environments and we offer the most popular sizes with Anti-Reflection Coatings. are also available for your application; please refer us Ge aspheric zoom lens for more information.

 

High resistivity hemispherical lens available

Available with AR or DLC coating

Available in a wide variety of diameters and focal lengths

 

Our germanium optics are all tested with our Zygo interferometer and spectrophotometer as standard testing items to ensure superior quality. Refer to our typical manufacturing specs for your information below. You can also contact us for manufacturing limit or custom specifications.
