Review EDMUND INDUSTRIAL OPTICS /20 Gold First Surface Mirror Optical Flat Metrology Lab

The Edmund Optics 43415/20 First Surface Mirror Optical Flat is a high-precision metrology tool designed for use in laboratories and other applications where accurate measurement of optical surfaces is essential. This optical flat features a first surface, uncoated, 20mm x 20mm (0.787 in. x 0.787 in.) zinc sulfide (ZnS) mirror, which provides superior reflectivity for visible and infrared wavelengths.

The mirror surface is precision ground and lapped to an absolute surface roughness (Ra) of less than 10 Angstroms, making it suitable for use in interferometric and other high-resolution measurement techniques. The flat's mirror surface is also tested for form error, ensuring that it is within the specified flatness tolerance of /10 at 633 nm.

The optical flat's body is made of high-precision machined aluminum, with a black anodized finish that provides excellent thermal stability and resistance to corrosion. The flat's edges are chamfered for easy handling and to prevent damage during use. The flat is also fitted with a removable protective cover to shield the mirror surface from dust and contaminants when not in use.

The optical flat includes a removable adjustable base, which allows for fine adjustments to be made to the flat's position and orientation. The base is also fitted with adjustable feet, which provide stability and allow for leveling on uneven surfaces. The flat can be easily mounted in a variety of ways, including directly on a table or using an optional clamping accessory.

The Edmund Optics 43415/20 First Surface Mirror Optical Flat is a versatile and essential tool for any metrology lab, providing accurate and reliable measurement of optical surfaces with high precision and repeatability. Its superior quality and rugged construction make it a durable and long-lasting investment for your laboratory or research facility.

Edmund Optics 43415/20 First Surface Mirror Optical Flat is a metrology-grade tool used for measuring and verifying the flatness of optical surfaces. Here are some pros and cons that can help you make an informed decision about purchasing this product:

1. High Precision: This optical flat has a surface figure error of lambda/4 at 632.8 nm, which makes it suitable for high-precision metrology applications.

2. Versatile: It can be used for measuring the flatness of a variety of optical components, including mirrors, windows, and lenses.

3. Durable: The mirror is made of high-quality borosilicate glass, which is resistant to scratches and other forms of damage.

4. Easy to Use: The optical flat comes with a micrometer and a vernier scale, making it easy to read and record measurements.

5. Interchangeable: Edmund Optics offers a range of interchangeable mirror surfaces for different wavelengths and applications.

1. Expensive: The optical flat is relatively expensive compared to other measurement tools, making it a significant investment for some users.

2. Requires Skill: Using an optical flat requires a certain level of skill and experience to obtain accurate measurements.

3. Limited Measuring Range: The optical flat can only measure flatness within its working range of 100 mm to 50 mm.

4. Sensitive to Environmental Conditions: The optical flat is sensitive to temperature and humidity changes, which can affect its measurements.

The Edmund Optics 43415/20 First Surface Mirror Optical Flat is a high-precision metrology tool that offers excellent accuracy and versatility for measuring the flatness of optical surfaces. However, its relatively high cost, limited measuring range, and sensitivity to environmental conditions are important considerations for potential buyers.

If you require high-precision measurements of optical surfaces and have the budget for it, the Edmund Optics 43415/20 First Surface Mirror Optical Flat is an excellent choice. However, if you have limited budget or measuring requirements, you may want to consider alternative measurement tools or contact Edmund Optics for a quotation on interchangeable mirror surfaces that better fit your needs.
