The Uses & Applications of Wave plates and Beam Splitters

Wave plates

Optical wave plates, often referred to as retarders, are devices that transmit light while altering its polarisation state without weakening, diverging, or shifting the beam. They accomplish this by delaying (or retarding) one polarisation component in relation to its orthogonal component. Their primary function is to control the polarisation condition of light beams. Both the slow axis and the fast axis of a wave plates are perpendicular to the direction of the beam and to one another. When polarisation is along the fast axis, the phase velocity of light is a little bit higher. Only a small wavelength range and a small range of incidence angles allow for the achievement of the intended magnitude of optical retardance.

Beam splitters

Beam splitters are optical devices that divide incident light into two distinct beams at a specified ratio. A glass plate with a thin layer of aluminium on it (often applied using aluminium vapour) is referred to as a splitter plate. The thickness of the aluminium coating is chosen so that only a portion of light struck at a 45-degree angle is transmitted and the rest is reflected. A dielectric optical coating may be employed rather than a metallic one. In the production of lasers, such mirrors are frequently utilised as output couplers. A pellicle mirror is a type of half-silvered mirror used in photography. Reflection/transmission ratios may change as a function of wavelength depending on the coating being utilised. Beam splitters can also be used backwards to combine two distinct beams into a single one. When polarisation state is not crucial, beam splitters are frequently utilised with unpolarised light sources like natural or polychromatic light. They are made to divide unpolarised light with unspecified polarisation inclinations at a particular Reflection/Transmission (R/T) ratio.

Selection Guide for Hot, Cold & Laser Mirror

Hot and cold mirror is a kind of mirrors with unique spectral properties, sometimes also called IR or heat control filters. Hot mirror reflects infrared (IR) light, while Cold mirror reflects visible and ultraviolet (UV) light.

Cold mirror (IR passing filter) is a specific dielectric mirror which is typically reflects visible light (nearly 95%) and transmits infrared wavelengths (90% of IR above 750 nm). A further case in point of this type of a mirror is a UV cold mirror, which reflects UV wavelengths and transmits visible and IR ranges. Conversely, Hot mirror (IR blocking filter) has reverse spectral physical characteristics. It reflects near infrared light and transmits the visible and UV ranges.

Both the types of mirrors can be designed and can be applied for specific angles of incidence, from 0° to 45°, though in practice a hot mirror typically operates at a low angle of incidence, whereas a cold mirror operates typically at 45° angle of incidence. Hot and cold mirror substrates are typically heat resistant glasses.

After hot & cold mirrors, let’s find out what is the application of Laser Mirror. Laser Mirror is the high reflection coatings designed for the use of laser reflection. They are designed for either single line, multi-line or broadband kind sources. For high reflection, strength and damage tolerance it must be coated with the hard, durable dielectric multilayer.
