Review THORLABS Inch Off axis Parabolic Mirror Prot. Ag Rfl

The Thorlabs MPD139-P01 90 Off-Axis Parabolic Mirror is an optical component designed for use in applications requiring high-reflectivity and high-quality parabolic mirror optics. This mirror features a 90 off-axis geometry, which is particularly useful in confocal microscopy and other applications where the light source and the detection point are located at different positions.

The MPD139-P01 mirror is made of high-quality borosilicate glass, which provides excellent optical properties including low thermal expansion coefficient, high thermal shock resistance, and excellent optical transmission in the visible and near-infrared spectral ranges. The mirror surface is coated with a broadband reflective coating that provides high reflectivity across a wide spectral range, from approximately 300 nm to 1100 nm.

The parabolic mirror surface of the MPD139-P01 mirror is precision-figured to ensure excellent optical performance. The mirror surface has an rms roughness of less than 1 nm, which is well below the wavelength of visible light, ensuring that the mirror surface does not introduce significant distortion or scatter to the incident light. The mirror has a diameter of 139 mm and a focal length of 100 mm, which provides a high f-number and excellent focus stability.

The MPD139-P01 mirror is designed for use in high-power applications, with a maximum recommended input power of 5 W. The mirror is also designed for use in vacuum environments and can be supplied with an optional bake-out oven to ensure reliable performance in vacuum applications.

The mirror is supplied with a protective cover plate to prevent dust and other contaminants from settling on the mirror surface. It also comes with a mounting flange that allows easy integration into optical systems using standard C14 threading. Overall, the Thorlabs MPD139-P01 90 Off-Axis Parabolic Mirror is an excellent choice for applications requiring high-reflectivity, high-quality parabolic mirror optics with 90 off-axis geometry.

The Thorlabs MPD139-P01 90 Off-Axis Parabolic Mirror is a high-quality optical component designed for various applications, particularly in telecommunications, fiber optics, and scientific research. Here are some pros and cons that can help you make an informed decision about purchasing this mirror:

1. High Reflectivity: This mirror has a high reflectivity of 99.5% in the wavelength range of 1260-1680 nm, making it an excellent choice for applications that require efficient light reflection.

2. Low Wavefront Error: With a wavefront error of less than /10 at 633 nm, this mirror ensures accurate and precise beam shaping, which is essential for many applications in fiber optics, telecommunications, and scientific research.

3. Robust Design: The mirror's robust design and rugged construction make it suitable for use in harsh environments. It is also resistant to temperature and humidity, ensuring long-term reliability and durability.

4. Versatile Applications: The MPD139-P01 mirror can be used in a wide range of applications, including fiber optic test sets, optical spectrometers, laser systems, and telecommunications equipment.

5. High Quality: Thorlabs is known for its high-quality optical components, and this mirror is no exception. It is manufactured using advanced techniques to ensure precise geometry and surface quality.

1. Limited Wavelength Range: While the mirror has high reflectivity in the 1260-1680 nm range, it may not perform as well in other wavelength ranges. Therefore, it may not be the best choice for applications that require reflection in the UV or IR regions.

2. Higher Cost: Compared to other mirrors in the market, the MPD139-P01 is more expensive due to its high quality and advanced features.

3. Size and Weight: The mirror is relatively large and heavy, which may make it less suitable for portable or compact applications.

4. Requires Precise Alignment: Due to its off-axis parabolic design, this mirror requires precise alignment to achieve optimal performance. This can be a challenge in some applications, particularly those where alignment is difficult to achieve or maintain.

In conclusion, the Thorlabs MPD139-P01 90 Off-Axis Parabolic Mirror is a high-performance, high-quality optical component that is ideal for applications in fiber optics, telecommunications, and scientific research where efficient light reflection and precise beam shaping are essential. Its rugged design, versatility, and high reflectivity make it a valuable investment for researchers and engineers working in these fields. However, its limited wavelength range, higher cost, size, and weight, and the need for precise alignment may make it less suitable for some applications. Ultimately, the decision to purchase this mirror depends on the specific requirements of your application and your budget. If the mirror's advantages align with your needs, then it is a worthwhile investment. However, if you have other requirements or budget constraints, you may want to consider other options.
