N-Bk7 Glass Optical Bi Concave Lens For Laser Beam Expansion & Collimation
Material:
N-Bk7 Glass: This lens is crafted from N-Bk7 glass, a high-quality optical glass known for its excellent transparency, low absorption, and good chemical resistance. N-Bk7 glass is a type of borosilicate glass that offers superior optical performance in the visible and near-infrared spectrum1.
Properties:
High Transparency: The lens exhibits high transparency, allowing for efficient transmission of light with minimal loss.
Low Absorption: N-Bk7 glass has low absorption in the visible and near-infrared range, ensuring that the lens does not heat up significantly when used with high-power lasers.
Good Chemical Resistance: The lens is resistant to a wide range of chemicals, making it suitable for use in harsh environments.
Excellent Surface Finish: The lens has a smooth, polished surface that minimizes scattering and reflection, ensuring optimal light transmission.
Functions:
Laser Beam Expansion: The bi-concave design of the lens allows it to expand a laser beam uniformly, increasing the beam's diameter while maintaining its coherence and intensity.
Collimation: The lens can also be used to collimate a laser beam, converting a diverging beam into a parallel beam, making it suitable for various optical applications.
Focal Length Adjustment: By adjusting the distance between the lens and the laser source, the focal length of the beam can be fine-tuned to meet specific requirements.
Applications:
Laser Systems: The lens is ideal for use in laser systems, such as laser cutters, engravers, and markers, where precise beam control and expansion are crucial.
Optical Instrumentation: It can be used in optical instruments, such as spectrometers and interferometers, for precise measurement and alignment.
Medical Devices: The lens is suitable for use in medical devices, such as laser treatment systems, where precise beam control is essential for safe and effective treatment.
Research & Development: The lens is also valuable in research and development applications, where it can be used to study the properties and behavior of laser beams in various conditions.
In summary, the N-Bk7 Glass Optical Bi-Concave Lens is a versatile and essential component for laser beam expansion and collimation. Its high-quality material, excellent properties, and precise functions make it an ideal choice for a wide range of applications in laser systems, optical instrumentation, medical devices, and research & development.
