These specifications provide detailed information about the SHAPE Optics Hemispherical (Half-Ball) Infrared (IR) Lens with a Calcium Fluoride (CaF2) substrate. Designed for applications requiring high numerical apertures, these lenses are suitable for UV to IR light coupling, including LED and fiber coupling, microscopy, and IR laser measurement.
Product Description:
- Hemispherical Design:
- Construction: Made by cutting a spherical (ball) lens in half, offering easier mounting and integration into optical systems compared to full spherical lenses.
- Applications:
- Fiber Coupling: Ideal for coupling light into optical fibers.
- Microscopy: Suitable for use in microscopy applications where high numerical apertures are beneficial.
- IR Laser Measurement: Useful in infrared laser measurement systems requiring precise light focusing and collection.
- Substrate-Specific Options:
- Fused Silica: Excellent for applications requiring UV to near-infrared (NIR) coverage.
- Silicon: Suitable for mid-wave infrared (MWIR) applications, available as standard hemispherical or hyper-hemispherical lenses.
- Calcium Fluoride (CaF2): Ideal for a broad range from UV to MWIR due to its high transparency and low absorption.
- Zinc Selenide (ZnSe): Best for long-wave infrared (LWIR) applications; however, special care must be taken due to its toxicity.
Safety Note:
- Handling Zinc Selenide (ZnSe):
- Toxicity: ZnSe is a toxic material. Always wear rubber or plastic gloves when handling to avoid contamination and exposure.
Conclusion
SHAPE Optics Hemispherical (Half-Ball) Infrared (IR) Lenses provide high numerical apertures and are ideal for applications such as fiber and LED coupling, microscopy, and IR laser measurement. With a range of substrates available, including Fused Silica, Silicon, Calcium Fluoride, and Zinc Selenide, these lenses cover a wide spectrum from UV to LWIR. The hemispherical design simplifies mounting, making them a versatile choice for various optical systems. Special care should be taken when handling Zinc Selenide due to its toxicity.
