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
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

Femtosecond, Picosecond – All wavelengths, 48 pages, 6 MB
TOPTICA offers several products: ultrafast fiber lasers based on Erbium (Er) and Ytterbium (Yb) like the FemtoFiber smart, FemtoFiber pro, FemtoFiber ultra and FemtoFiber dichro series. All these systems are based on TOPTICA FemtoFiber technology.
UV, Visible, Infrared - Digital Control - Wavelength Stabilization, 52 pages, 7.9 MB
TOPTICA's tunable, single-frequency lasers are available for individual wavelengths between 190 nm and 4000 nm, and deliver narrow-linewidth emission that is tunable – in some systems up to 120 nm wide without a single mode-hop.
Lasers for Terahertz Systems and Accessories, 32 pages, 5.5 MB
TOPTICA provides complete systems and components for both time-domain and frequency-domain terahertz generation. Selected accessories – Schottky diodes and optomechanics – are available for both time-domain and frequency-domain systems.
Compact, robust, high end – and convenient, 16 pages, 4.4 MB
Frequency combs are very precise tools which are used for applications that require highest accuracy and resolution when measuring the frequency of light. A frequency comb has an optical spectrum that consists of equidistant lines in the frequency domain.
TOPTICA at a glance: product overview, 12 pages, 2 MB
The TOPTICA portfolio includes diode lasers, ultrafast fiber lasers, terahertz systems and frequency combs. OEM customers, scientists, and over a dozen Nobel laureates all acknowledge the world-class exceptional specifications of TOPTICA’s lasers, as well as their reliability and longevity.
Single-Mode Diode Lasers, 16 pages, 4 MB
Colorful diode lasers for a Variety of applications – 375nm - 850nm: our ind. diode lasers combine first class diode technology and rock-solid opto-mechanical engineering, completed by convenient computer-control and intelligent protection measures. With cw or pulsed operation, TEM00 mode and a spectral linewidth of typically 0.5 nm.
Fully Featured Multi-Color Laser Engines, 16 pages, 6.6 MB
The iChrome family of multi-laser engines addresses the need for lasers with multiple colors in biophotonics (microscopy, cytometry, DNA sequencing etc.) and metrology (scatterometry, ellipsometry).
Single-Frequency Diode Lasers, 6 pages, 3.9 MB
The TopMode series sets records in terms of power, coherence and wavelength stability. The proprietary CoHerence-Advanced Regulation Method (CHARM) provides an active stabilization of the lasers’ coherence and ensures continuous single-frequency operation.
