Review THORLABS Inch Protected Aluminum Elliptical Mirror 450 Nm Um

The Thorlabs PFE20-G01 protected elliptical mirror is a high-performance optical component designed for applications in the ultraviolet and visible spectral regions. This particular mirror has a protective coating optimized for 450 nm wavelength and a mirror surface finish with a root mean square (RMS) roughness of 20 nm.

The mirror's elliptical shape is ideal for applications where an elliptical reflecting surface is required, such as in laser cavities or other optical systems where precise shape control is essential. The mirror's major and minor axes have radii of curvature of 1000 mm and 500 mm, respectively, ensuring excellent figure and surface quality.

The protective coating on the PFE20-G01 mirror is essential for maintaining the mirror's performance in demanding environments. The coating is designed to provide excellent scratch resistance, making the mirror suitable for use in applications where it may be exposed to mechanical stress or abrasive particles. The 450 nm optimization ensures that the mirror reflects efficiently in the blue region of the visible spectrum.

The mirror's substrate is made from high-quality borosilicate glass, which provides excellent optical properties and resistance to thermal shock. The mirror's high reflectivity, combined with its excellent surface quality and protective coating, make it an excellent choice for a wide range of applications in the fields of laser technology, spectroscopy, and other areas of optical research and development.

The PFE20-G01 elliptical mirror is available in various sizes, with a diameter of 20 mm and a thickness of 5 mm as standard. Custom sizes and coatings are also available upon request. The mirror is supplied in a protective package to ensure safe handling and transport.

In summary, the Thorlabs PFE20-G01 protected elliptical mirror is a high-quality, versatile optical component suitable for use in a wide range of applications in the ultraviolet and visible spectral regions. Its elliptical shape, protective coating, excellent surface quality, and high reflectivity make it an excellent choice for applications where precise shape control and efficient reflection are essential.

The Thorlabs PFE20-G01 protected elliptical mirror with a reflection wavelength of 450 nm and a surface figure error of 20 um is a high-precision optical component designed for applications in laser systems and other optical setups. Like any other product, it comes with its own advantages and disadvantages.

1. High Reflectivity: This mirror has a high reflectivity at the wavelength of 450 nm, making it an excellent choice for applications where maximum reflection is required.

2. Protected Design: The mirror is protected by a front window, which shields it from external contaminants and damage. This feature is particularly important in environments where particle contamination is a concern.

3. Low Surface Figure Error: With a surface figure error of 20 um, this mirror offers excellent surface quality, which is crucial in applications where the beam shape needs to be maintained.

4. Durable: The mirror is made of high-quality materials that ensure its durability and long-term performance.

1. Limited Wavelength Range: This mirror is specifically designed for use at a wavelength of 450 nm. If your application requires reflection at a different wavelength, you may need to consider a different mirror.

2. Higher Cost: Due to its high-precision design and materials, this mirror comes with a higher price tag compared to standard mirrors.

3. Size Limitations: This particular model has a diameter of 20 mm, which may not be suitable for all applications. Larger or smaller diameters may be available upon request but may come with additional costs.

The Thorlabs PFE20-G01 protected elliptical mirror with a reflection wavelength of 450 nm and a surface figure error of 20 um is a high-precision optical component that offers excellent reflectivity, surface quality, and protection against external contaminants. Its limited wavelength range, higher cost, and size limitations are potential drawbacks that should be considered depending on your particular application requirements.

If you require high-precision reflection at a wavelength of 450 nm with excellent surface quality and protection against contaminants, the Thorlabs PFE20-G01 protected elliptical mirror is an excellent choice. However, if your application requires reflection at a different wavelength or a different mirror size, you may need to explore other options.

Details:

This unit will arrive in the condition shown. The protected aluminum coating has a smaller chance of tarnishing than silver in high humidity environment, and gives reluctance that most closely matches the bare. An SiO2 coating is used to protect the delicate aluminum coating, making it suitable for laboratory and industrial use. Power cords and power adapters are never included unless specifically mentioned.
