Review THORLABS / LIGHTPATH Geltech Lens 2.75mm Aspheric Fl

The Thorlabs 355390-B 600nm-1050nm GelTech Lens is a high-quality optical component designed for applications requiring precise light manipulation within the near-infrared spectrum. This lens features a focal length of 2.75mm and an aperture of 0.55, making it a compact yet powerful tool for focusing or collimating light.

The lens is made of GelTech material, a type of optical glass that provides excellent thermal stability and resistance to shock and vibration. This makes it an ideal choice for applications where temperature fluctuations or mechanical stresses may be present.

The lens is also characterized by its aspheric design, which helps to minimize spherical aberrations and distortions, ensuring that the output light is as close to a perfect plane wave as possible. This results in improved image quality and reduced loss of light.

The Thorlabs 355390-B GelTech Lens has a numerical aperture (NA) of 0.55, which indicates its ability to collect and focus light. A high NA means that the lens can collect more light and focus it more tightly, making it more suitable for applications that require a high level of light intensity.

This lens is available in a threaded version (355390) and a bare version (355390-B), allowing you to choose the most suitable mounting option for your specific application. Both versions are designed to meet high standards of optical performance and mechanical durability, ensuring reliable operation over time.

In summary, the Thorlabs 355390-B 600nm-1050nm GelTech Lens is a versatile and high-performance optical component, ideal for applications in the near-infrared spectrum that require precise light manipulation and thermal stability. Its compact size, high NA, and aspheric design make it a powerful tool for focusing or collimating light, while its durable GelTech material ensures reliable operation in various environmental conditions.

1. Wide spectral bandwidth: The lens covers a broad wavelength range from 600nm to 1050nm, making it suitable for various applications that require non-visible light, such as fluorescence microscopy, laser processing, and fiber optics.

2. Aspheric design: The lens has an aspheric surface, which helps reduce spherical aberration and ensures a high-quality image with improved sharpness and contrast.

3. Low NA (numerical aperture): The lens has a low NA of 0.55, which allows for better depth of field and less light scattering, making it ideal for applications requiring good optical resolution and minimal light loss.

4. High-quality materials: The lens is made from GelTech, a high-refractive-index material, which ensures excellent optical performance and durability.

5. Threaded mount: The lens has a 32mm threaded mount, allowing for easy integration with various optical systems and setups.

1. Limited aperture: The low NA of the lens may limit the amount of light that can be collected, which could be a drawback for applications requiring high light levels.

2. Limited field of view: Due to its small size, the lens may not provide a wide field of view, which could be a limitation for certain applications.

3. Higher cost: The lens may be more expensive than other lenses with a smaller spectral range or lower optical performance, which could be a factor for budget-constrained applications.

The 600nm-1050nm GelTech Lens 2.75mm 0.55 NA Aspheric from Thorlabs (Part Number: 355390-B) is a high-quality optical component that offers excellent performance for applications requiring non-visible light. Its wide spectral bandwidth, aspheric design, low NA, and high-quality materials make it an ideal choice for a variety of applications, such as fluorescence microscopy, laser processing, and fiber optics. While it may have some limitations, such as limited aperture and field of view, and a higher cost compared to other lenses, its superior optical performance and durability make it a worthwhile investment for many applications. Overall, we recommend considering this lens for applications requiring high-quality, wide spectral range optical performance in the 600nm-1050nm wavelength range.
