Introduction to Micro Drum Convex Lenses

Micro drum convex lenses, made from high-quality fused silica or K9 glass, are optical components that play a crucial role in various advanced technologies. Particularly in fields like 5G communication and medical applications, these lenses enhance the performance of imaging and light manipulation systems.

Our range of drum and half drum lenses can be manufactured from a range of materials;N-BK7 or equivalent is typically used in visible applications. Quartz and UV grade fused silica is used for applications working in deep UV wavelengths down to185nm; these materials are also useful in the NIR wavelengths up to 2000nm. A range of high index materials such as Lasfn9, Lasf35, S-Lah65 and Lah78 are available for very short focal lengths with minimal spherical aberrations.

Specifications of Micro Drum Convex Lenses

The dimensions of micro drum convex lenses can vary, with a diameter range of 1.5mm, 2mm, and 3mm available. Each lens features a length of either 2.6mm or 1.8mm, tailored to meet specific application requirements. Notably, these lenses are manufactured with stringent tolerances of +0/-0.05mm, enhancing their precision in optical systems.

One essential attribute of micro drum convex lenses is their clear aperture, which covers the central 90% of the lens dimensions. This feature is particularly beneficial in ensuring that most of the incoming light passes through the lens unobstructed, maximizing efficiency. Furthermore, the centering of these lenses is maintained at 30 arc minutes, providing high-quality optical performance.

Performance Characteristics and Coatings

In terms of surface quality, micro drum convex lenses are rated at 60-40 scratch-dig, ensuring minimal surface imperfections. Such quality is critical for applications requiring high clarity and precision, as any flaws can significantly impact performance.

Moreover, the lenses are often coated to enhance their functionality. The coatings are optimized with reflectance values of 3%@200-850nm and 4%@850-900nm, which help to minimize light loss and improve transmission efficiency. These characteristics make them ideal for high-performance applications, particularly in the fast-evolving field of 5G communication.

Applications in Modern Technology

Micro drum convex lenses are increasingly utilized in various sectors due to their exceptional properties. In 5G communication, the precision of these lenses allows for improved signal clarity and transmission speed, significantly enhancing the overall network performance. Similarly, in medical applications, these lenses contribute to advanced imaging systems and diagnostic devices, allowing for high-resolution imaging with minimal distortion.

Their compact size and high-quality construction ensure that micro drum convex lenses fit seamlessly into modern electronic devices, facilitating the ongoing advancements in both telecommunications and healthcare technology.

Conclusion

In conclusion, micro drum convex lenses represent a significant advancement in optical technology, offering a compelling combination of precision and performance. Their specifications, including tight tolerances and optimized coatings, position them as vital components in contemporary applications, especially in demanding fields such as 5G communication and medical imaging. As technology continues to evolve, the importance of such optical components will undoubtedly increase.
