Gradient Index Lens-Glens

Description

Introducing the GradientIndexLens by Hobbite.Co., Ltd, a cutting-edge optical component designed to meet the highest standards of precision and performance. This lens is meticulously crafted to deliver exceptional optical clarity and efficiency, making it an ideal choice for a wide range of applications. With its advanced gradient index technology, this lens offers superior light transmission and minimal distortion, ensuring optimal performance in even the most demanding environments.

The GradientIndexLens is engineered with precision, featuring a standard diameter of φ1.8mm with a remarkable tolerance of ±0.005mm. This ensures consistent quality and reliability in every lens produced. The lens is available in multiple pitch options, including 0.23P and 0.25P at both 1550nm and 1310nm wavelengths, providing flexibility to suit various optical systems. Its numerical aperture of 0.460 allows for efficient light collection and transmission, enhancing the overall performance of the optical system.

Designed with an endface angle of 8°±30', the GradientIndexLens minimizes reflection loss, achieving an impressive reflection loss of less than 0.5% at 1550nm or 1310nm. This feature significantly reduces signal loss and enhances the quality of the transmitted signal. Additionally, the lens boasts an insertion loss of P grade ≤0.15dB and A grade ≤0.20dB, ensuring minimal signal attenuation and maintaining the integrity of the optical signal.

For those with specialized requirements, the GradientIndexLens offers a specially designed and processed product index range. This includes a variety of diameters from 1.0mm to 4.2mm, pitch options ranging from 0.10 to 0.50, and numerical apertures of 0.37, 0.46, and 0.60. The lens can accommodate wavelengths from 380nm to 2000nm, with a bandwidth of ±150nm for single wavelength and ±50nm for dual wavelength applications. This versatility makes it an excellent choice for customized optical solutions.
