Top 10 Questions for Precision Optical Goods Worker Interview

1. What is the difference between optical glass and ordinary glass?

Optical glass is a type of glass that is specifically designed for use in optical applications, such as lenses and prisms. It is made from a high-quality base glass that is then carefully melted and cooled to form a uniform material. Optical glass has a number of important properties, including:

• High clarity: Optical glass is very clear and has a low refractive index, which means that it allows light to pass through it with minimal distortion.
• Low dispersion: Optical glass has a low dispersion, which means that it does not cause light to spread out into different colors when it passes through it.
• High durability: Optical glass is very durable and can withstand a wide range of temperatures and other environmental conditions.

2. What are the different types of optical coatings?

Anti-reflection coatings

• Anti-reflection coatings are applied to optical surfaces to reduce the amount of light that is reflected from the surface.
• This can improve the transmission of light through the optical system and reduce the amount of glare.

Reflective coatings

• Reflective coatings are applied to optical surfaces to increase the amount of light that is reflected from the surface.
• This can be used to create mirrors or to redirect light.

Beamsplitter coatings

• Beamsplitter coatings are applied to optical surfaces to split a beam of light into two or more beams.
• This can be used to create beamsplitters or to combine multiple beams of light.

3. What is the process of optical grinding and polishing?

Optical grinding and polishing is a process used to create optical surfaces with a high degree of precision. The process involves using a grinding wheel or polishing pad to remove material from the optical surface. The grinding wheel or polishing pad is typically made of a hard material, such as diamond or sapphire.

• The grinding process is used to remove large amounts of material from the optical surface. The polishing process is then used to create a smooth, high-quality surface finish.
• Optical grinding and polishing is a skilled trade that requires a high degree of precision and attention to detail.

4. What are the different types of optical testing methods?

There are a number of different optical testing methods that can be used to measure the performance of optical components.

• The most common type of optical testing method is interferometry. Interferometry is a technique that uses the interference of light waves to measure the surface shape of an optical component.
• Other optical testing methods include:
  • Spectrophotometry
  • Polarimetry
  • Scatterometry

5. What are the different types of optical manufacturing processes?
