Polarimeter— Stress Measurement for Laser Window

The Laser window is used to separate the environment on both sides, such as separating the inside and the outside of the instrument . In this way, the inside and the outside of the instrument are isolated from each other, thereby protecting the internal components. The window is the basic optical element, which is an optical flat plate. It does not change the optical magnification, but only affects the optical path in the optical path. The windows are all coated with anti-reflection coating or without anti-reflection coating. In addition to protecting the laser window, it must also ensure high transmittance and excellent transmitted wavefront. The performance of laser windows is quite different from ordinary optical windows. Its main applications include: laser cutting head protection, optical observation windows, laser protection windows, etc. When choosing a laser window, materials, transmittance, scattering, wavefront distortion, parallelism and the corresponding working environment are all factors that need to be considered

When talking about different applications , ZnSe windows, Ge windows, Si windows, BaF₂ windows, and CaF₂ windows are used in the infrared spectrum; fused silica windows and sapphire windows are used in the ultraviolet spectrum; K9 window is used in the visible light spectrum. The main applicable wavelengths are 532nm/1064nm/1070nm wavelength of fiber laser and 10.6μm wavelength of CO2 laser.

When choosing a window, important parameters should be considered including light transmittance, surface accuracy, thickness, parallelism, substrate material and other properties. Commonly used substrate materials include BK7, UV fused silica, K9 glass ,CaF₂ , Si, Ge, Zn, Se, etc. The corresponding preparation methods include single crystal growth, chemical vapor deposition, hot pressing or isostatic pressing sintering and so on. Since many defects in the preparation process of the subscrates are invisible to the naked eye, this requires us to use some optical equipments for quality control. One of the most widely used instrument is the Polarimeter.

The measurement of a Polarimeter is based on the detection of stress birefringence. For instance , glass is a kind of isotropic object. The refractive index in each direction is the same. If there is stress in glass, the isotropic property will be destroyed, causing a change in refractive index. The refractive index of the two principal stress directions will no longer be the same, thus leading to birefringence .

When birefringence occurs , a Polarimeter can be used to measure optical retardation. Based on experiments , relationship between optical retardation value and the stress value is determined by a special formula. As long as optical retardation value can be measured, the residual internal stress value can be calculated . At present, most Polarimeters are designed to measure optical retardation value directly .

Things to Consider When Ordering Optical Flats

Optical flats, also known as “test flats”, “test plates” or “reference flats” are precisely polished surfaces that are used to measure the flatness (surface accuracy) of an unknown surface. They do so by using the property of interference.

When optical flats are placed on a test surface, an air wedge forms where the two surfaces don’t touch. The thickness of the air wedge is analyzed to find out the shape and direction of the interference bands, which helps in determining the flatness of the test surface.

When viewed under monochromatic light, the two surfaces show light and dark bands, called interference fringes. If these interference fringes are parallel and straight, the test surface will be said to have more than or equal flatness compared to the reference surface. Conversely, an uneven interference pattern shows that the test surface’s flatness is lesser than that of the reference flat.

Common flat optical components used in the IR, UV and visible spectrums are:

· Filters

· Wedges

· Mirrors

· windows

· Waveplates

· Encoder disks

· Debris shields

· Reference surfaces

· Light pipes

· Gratings

Factors to Consider

Here are some factors you need to consider when ordering optical flats:

Optical Material

Homogeneity, bubbles, and stress birefringence are some of the most important factors since they affect product performance, quality, and pricing.

For instance, an optician’s ability to achieve the desired transmitted wavefront specification goes down as the product’s homogeneity decreases. Similarly, stress birefringence impacts the mechanical stability of the test surface. Bubbles, on the other hand, can affect the product’s cosmetics during the polishing and grinding stages.

Best optical materials for single and dual surface flat optics are BK7 and fused silica. While other materials can also be used, they require special processing techniques and careful handling as they might be sensitive to humidity or temperature.

Wedged or Parallel

Components like plate beam splitters, filters, windows, and wafers typically need to be of high parallelism, whereas wedges and prisms may be intentionally wedged.

Factors like polishing and grinding play a crucial role in achieving the desired parallelism specifications. Double-sided polishing and grinding are one of the best methods to achieve exceptional parallelism (i.e. <1 arc second). Manufacturers measure parallelism using an interferometer.

Conversely, prisms and wedges are processed using pitch polishers to achieve the required angled surfaces.

Dimensions

Although optical flats are of various shapes, round optics are the best in achieving desired specifications uniformly and quickly.
