It is valid for visible light, continuous wave (CW) lasers such as laser pointers and laser light show projectors. This site is home to The Evaluator – LIA's Web-based Laser Safety Hazard Analysis System; providing a reliable way to easily double-check laser safety calculations. Specially designed for users with minimal experience, the Basic package provides the essential and fundamental laser hazard calculations in an easy and simple format. For other shape pulses, the result will not be completely accurate. Plus, you can easily upgrade or downgrade to any subscription level at any time — making it a flexible and scalable solution for dynamic organizations. Note: The Synrad Beam Propagation Tool requires the Java Version 8 (or newer) runtime installed on your PC. The results include a description of the cutting or marking operation along with speed and/or cycle time information and a photograph showing results of actual laser processing on the selected material.

Both versions of the Evaluator offer users an easy and seamless experience, assisting LSOs of all skill levels complete necessary safety calculations in the field. A Class 4 laser or laser system is any that exceeds the output limits (Accessible Emission Limits, AEL's) of a Class 3 device. Our staff will continue to offer customer support by phone or email during our regular operating hours. The AEL for Class 3R is limited to 5 times he AEL of Class 2 (visible laser radiation) or 5 times the AEL of Class 1 (for non-visible laser radiation). More options to fine tune the accuracy of your calculations, Any revisions to the standard during your subscription will be immediately reflected in the system, Definitions and references from the current ANSI Z136.1 standard provided for keywords and acronyms, Experiment with various laser, eyewear or barrier combinations with enhanced interactive graphic displays, Graphically illustrates use of eye protection, shows difference between, Elliptical, Rectangular, and TopHat Profiles, Computer requirements: Windows 7, 8, or 10 and PDF viewer (such as Adobe PDF).
As would be expected, these lasers may be either a fire or skin hazard or a diffuse reflection hazard. Laser Institute of America - Free OD Calculator This convenient online tool will calculate the recommended optical density for use with a laser system of a given power.
Professional-level LSOs will appreciate the more advanced features in this package including source size, laser database, range, aided viewing, atmospheric attenuation, limiting aperture, OD at Range and graphs. As a software program stored on the computer, the Desktop Evaluator eliminates the need for internet access. Now with three monthly subscription packages and pricing levels to choose from: Advanced, Intermediate, or Basic, your organization has the flexibility to pay for only the features it needs. This innovative System provides a reliable way to easily double-check laser safety calculations. This site is home to The Evaluator – LIA's Web-based Laser Safety Hazard Analysis System; providing a reliable way to easily double-check laser safety calculations. The laser pulse energy calculation explained, with numerical examples. Unitatea centrală; 3.
Desktop - Single User - One Time Purchase, Change laser settings by easily switching between CW, Single Pulse or repetitively pulsed lasers as well as adjusting the beam profile (circular, elliptical or rectangular), Designed for today’s LSO – save reports*, view graphs* and make suggestions for new features, Easy Navigation, Accurate Results! If necessary, click the Java download button below to download the latest version. This calculator assumes square pulses. Terms & Conditions - Corporate Citizenship. Evaluare; 4. Usr our optical calculator to calculate different laser beam parameters including: M2, beam divergence, Rayleigh length and more Get free consultation: +972-733133232 holoor@holoor.co.il Medical facilities, small colleges, education institutions and other organizations with basic laser equipment and applications would benefit greatly from this affordable and practical laser safety hazard software package. For beams that are not 100% uniform, the peak power/energy density will be higher. Laser Institute of America (LIA). When upgrading to Intermediate from the Basic package, the additional features include elliptical, rectangular, and tophat profiles, focused beams, classification, exposure time, MPE skin, reflections, laser barriers and reports. It is a must-have for experienced and highly skilled LSOs working in research facilities, government, military, and advanced laboratories. It provides minimal hazard calculations including MPE, Optical Density, Intrabeam NOHD, and worst case Diffuse Reflection NHZ for CW, Single Pulse, and Repetitive Pulse lasers.

Disclaimer: All information and material posted on this Website are subject to copyrights owned by the For NOHD calculations, the wavelength (color) does not matter. Unlike the web-based system, the Desktop Evaluator is delivered on a USB drive, from which users can download the program to their computer. Our website uses cookies to deliver many of our products and services, to better secure your data, for analytics, and to provide you a with a more personalized experience. If you don’t know the beam divergence, use a value of 1 milliradian for lasers under 500 mW, and 1.5 milliradians for lasers 500 mW and above. The user-friendly navigation makes calculating eye hazards, wavelength, pulse width and other important calculations easier for novice users.
To calculate the NOHD, you need to know the laser’s power in milliwatts (mW) and the beam divergence in milliradians (mrad). Our company is a leader in the CO2 laser industry with an ongoing commitment to product excellence and superb customer service. If you are trying to calculate the amount of energy that is contained in your laser pulses, you are either working with a pulsed laser and want to know the energy in each individual pulse, or with a CW or pulsed laser that is fired for a known and finite amount of time. Please revise your search by enlarging beam diameter, reducing power, energy, pulse rate, etc.
I like being a part of this great team, which has those goals each day.”, Craig Willis Compatible with Windows 7, 8 or 10 PDF viewer, the easily downloadable program – which most closely resembles the web-based version’s advanced subscription level – lives on your computer, offering constant, uninterrupted access.
