These specifications provide detailed information about the SHAPE Optics Hemispherical (Half-Ball) Infrared (IR) Lens with a Silicon (Si) substrate. Designed for applications requiring high numerical apertures, these lenses are suitable for mid-wave infrared (MWIR) applications such as fiber and LED 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 compared to full spherical lenses.
- Applications:
- Fiber Coupling: Perfect for fiber coupling applications where high numerical apertures are essential.
- Microscopy: Suitable for microscopy applications that require precise light focusing and collection.
- IR Laser Measurement: Ideal for infrared laser measurement systems requiring accurate light control and high numerical apertures.
- 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 risks.
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. Available with a range of substrates 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 versatile for various optical systems. Special care should be taken when handling Zinc Selenide due to its toxicity.
