Lens Material Options: Glass vs. Plastic
Glass lenses offer high durability and precision, making them suitable for environments where consistent optical performance is critical.
Plastic lenses provide a budget-friendly option for less demanding applications, where moderate performance is sufficien.
Both options are available with anti-reflective coatings customized for specific wavelengths, enhancing transmission efficiency and reducing optical losses.
Applications
Medical Imaging and Diagnostics:
Collimated beams enable precise targeting in laser-based surgical tools and diagnostics equipment.
Optical Alignment and Process Control:
Accurate beam collimation is critical in metrology, ensuring that measurements remain consistent across various environments.
Telecommunications and Sensor Systems:
Collimating lenses are integral to fiber optic systems, enhancing signal clarity and minimizing loss during transmission.
Why Us
Many laser applications face challenges such as beam divergence, alignment issues, and aberrations that degrade performance. Users often struggle with configuring lenses to ensure precision while maintaining mechanical stability. Furthermore, delays caused by sourcing specialized optics and technical difficulties in achieving consistent beam quality can halt progress in industries like medical imaging, metrology, and communications.
Aspheric Lens Technology
Reduces spherical aberration, delivering high-quality collimated beams without distorting the wavefront.
Flexible Configurations
Solutions available for single-emitter diodes, VCSEL arrays, and broad-area emitters, addressing different beam profiles and power levels.
Pre-Engineered and Customizable
We can provide standard collimators and custom designs to meet specific application requirements
Solutions for Common Challenges
Beam Divergence
Laser diodes emit beams with varying divergence angles along different axes, often resulting in elliptical outputs. Adding cylindrical lenses corrects the shape, while fiber coupling filters out aberrations for a near-perfect Gaussian beam.
Misalignment Issues
Adjustable lens mounts and rugged housings ensure precise alignment, helping systems maintain consistency even in harsh environments.
Custom Needs and Fast Deployment
Ready-made collimators ensure quick turnaround for industrial projects, while OEM packages provide tailored solutions with reduced lead times for large-scale operations.
