Beam Divergence of a laser beam is an angular measure of the increase in the beam diameter or the radius with the distance from the beam waist, from where the beam diverges.

Near infrared light is closest in wavelength to visible light and far infrared is closer to the microwave region of the electromagnetic spectrum. The ...

Longpass filters are used in optical setups such as monochromators and spectrometers to suppress the higher diffraction orders of the optical grating.

Feb 16, 2023 — So, lenses from 14mm-24mm are considered wide angle lenses. Telephoto lens. A telephoto lens generally has a focal length of 60mm or longer.

It is found that practically the laser beam cannot focus on a point, instead, there is a small beam thickness at the focal point. This smallest distance up to which a laser beam can converge is known as the beam waist (w0). It is basically the focal point of a laser beam.

Parallel (Horizontal) beam divergence is the angular measure of the increase in the beam diameter along the optic axis, i.e. along the Z-axis as in the figure.

In the case of a longpass filter, the cut-on wavelength, the actual blocking band, the transmission band and the optical density are important for the filter’s specification.

Beam diameter is calculated in terms of beam diameters at two different points far from the rayleigh range and the distance between these points.

Let Df and Di be the beam diameters at two different points away from the rayleigh range and let l be the distance between them. Then beam divergence (θ) is given by,

ShortpassFilter

A longpass filter only allows light to pass above a certain threshold wavelength. It blocks the light below this wavelength.

Rayleigh range (ZR) is the distance from the beam waist where the beam radius has increased √2 times its initial value. This is the point at which the area of cross-section is doubled.

Perpendicular (Vertical) beam divergence is the angular measure of the increase in the beam diameter along the axis perpendicular to the optic axis, i.e. along the Y-axis as in the figure.

The wavelength range in which the light is blocked by the longpass filter is called the blocking band. The unit for the quality of blocking is usually given as the optical density (OD) and this is an essential feature of a filter’s quality. Long pass filters are available both as interference filters and as coloured glass filters, and are used, for example, in spectrometers and monochromators to suppress the higher orders of the diffraction grating. In this case they are also called order sorting filters.

A longpass filter is an optical filter that blocks incident light below a certain wavelength and allows light above this wavelength to pass through. This threshold wavelength is also called the cut-on wavelength. When choosing the right longpass filter, in addition to the cut-on wavelength, the actual blocking band must be taken into account. This is because the longpass filter is still permeable to the smallest parts of light. The transmission band of the filter also plays a role, the upper limit of which is dependent on the substrate used.
