Calculator for Laser Optics
ToptiCalcTM is TOPTICA Photonics scientific calculator specially designed for use in optics laboratories. We dedicate this helpful calculator to our customers, physicists and engineers, people that work hard in order to make optics and lasers useful for science and industry. It is free and we hope it can help to make some of your calculations easier!
You are a physicist reading a chemistry paper. Why do they always use wavenumbers instead of wavelengths...? ToptiCalcTM helps you in your everyday laboratory life by offering simple but pratical optics calculations like:
- Spectral unit conversion
- Calculating spot sizes for focussed Gaussian beams
- Fabry-Perot calculations
- Reflection and diffraction at plane glass surfaces
- Pulse train calculations
- Short pulse properties and chirp
- Conversion between linear and decibel scale
Special features of ToptiCalc™ (PC-version only):
Feature Comment Mathematical expressions are entered via a simple intuitive syntax Simply enter the calculation like you would write it down. ToptiCalcTM supports the operators + , - , * , / , ^ (power) and the predefined functions sin (x), cos (x), tan (x), arcsin (x), arccos (x), arctan (x), sqrt (x), exp (x),
ln (x), log (x) and pi
Dots AND commas are accepted as decimal separators Dots AND commas are accepted as decimal separators A history list collects all entered expressions and the calculated results You can always check whether you really entered the correct expression With a double click on the history list an old expression can be inserted into the current expression You can easily modify earlier calculations or use and combine earlier results for new calculations With a right-click selected parts or the complete history list can be transferred to the clipboard You easily insert your calculations and results into any text Important fundamental constants are available in SI units (feature 'const SI') A convenient selection of fundamental constants saves frequent looking up in textbooks Spectroscopic constants are available in convenient and useful 'lab units' (feature 'const lab') Often the SI units are too awkward for real laboratory life. If you want to e.g. translate the optical path length (which you measured with your ruler in millimeters) into a temporal delay in picoseconds its much more convenient to have the speed of light directly in mm/ps.... Thus ToptiCalcTM provides some important fundamental constants in common alternative units Arbitrary functions and variables can be defined by the user You can easily define your own frequently needed functions and constants, and save them to your harddisk.
Do you often need to calculate an index of refraction of your glass for different wavelengths? Just define the relevant Sellmeier function. Or do you often need Planck's constant for translating frequencies into energies? Simply define a constant h.Pressing CTRL+X in the input line or or right-clicking in the history list provides a very easy and quick way to define a variable with the value of the current expression or any older calculation, respectively
