Beam Shaper Quality Calculator:

This calculator estimates the likely quality of a single-mode beam shaper optic. By inputting a set of optical train parameters, it calculates an indicator of beam shaper quality. When shaping a single-mode laser beam, the beam shaper optic modifies the local surface slope to continuously map the input power distribution (Gaussian) to the desired output distribution. As a result, the shaped spot will always be larger than the diffraction-limited spot size due to added divergence. The beam shaper quality indicator is based on the ratio between the unshaped spot size and the shaped spot size.

By utilizing these calculators, PowerPhotonic aims to simplify the design process and provide valuable insights into lens parameters, spot size limitations, and beam shaper quality.

Designing and manufacturing high-performance micro-optics can be a challenging task. PowerPhotonic offers optics calculators to simplify this process and determine crucial characteristics of optical surfaces, including lens specifications, manufacturability, and beam quality.

Lens Calculator:

The lens data calculator determines key surface parameters based on the lens diameter and required focal length. It helps assess if the desired surface is manufacturable and suggests modifications to bring it within the feasible range.

Spot Size Calculator:

The spot size calculator determines the smallest spot that a perfect lens with a Gaussian input beam can create, considering diffraction limitations. Users can vary the input beam size, lens focal length, and wavelength to observe changes in the diffraction-limited spot size.At PowerPhotonic, this information aids our engineering team in determining the minimum size of a shaped beam. All beam shapers introduce divergence, which means a shaped beam cannot be smaller than the system’s diffraction-limited spot size.
