LaserBee Version History


BS EN 207:2017 implemented; previous version BS EN 207:2009 still supported but earlier version removed.


An error in the calculation of MPEs and AELs when using BS60825-1:2014 for repetitively pulsed lasers with wavelengths in range 1400 nm < lambda < 105 nm and pulse durations < 1 ns is corrected. The divergence calculation type is now included in TAB summary pages.


Lack of 60825-1:2014 ‘dual apertures’ warning and consequent classification error corrected (gave Class 1 in some cases when should have been 1M). The 60825-1 version in use was added to report file.


Several improvements made to clarify whether a linear divergence expression or a Gaussian beam divergence expression was being used.  Bug concerned with switching from an elliptical beam back to a circular beam corrected.


Irrelevant short pulse warning removed.
EN 207 CW laser < 30000 s exposure made type ‘I’ rather than ‘R’.


A major re-write to comply with IEC 60825-1 ed.3, BS EN 60825-1:2014.


Minor input routine modification to make all tools work from startup for any user entry.


The rad/mrad/urad input on the geometry tab now works.


Numeric Aperture input problem for multimode fibres corrected.


New Diffuse Reflections Tool added. Calculates Irradiance / radiant exposure at specified distance, NOHD and required OD for a variety of different models.


Obscure input error when cycling between cw / repetitively pulsed / single pulse modes corrected


EN 207:1999 output changed to quote both pulsed and equivalent CW scale for repetitively pulsed lasers.
Reading of laser database files changed to accept “.” or “,” as the decimal separator.
Tab summary button only enabled when data available


Layout and display improved.
Upgrade notification mechanism improved.
Added option in EN 207 to use pulse or average power for repeated long pulses


Option to apply C5 to Class 3B AELs added.
Obscure scrambled text error in Windows 7 64 bit Dutch machines corrected’
Fixed 207 beam diameter preferences


Tab summary for Classification tab added giving details of condition 1, 2 and 3 measurements.
Upgrade notification mechanism added to alert users to availability of new upgrades.
Extended source labelling error corrected on Subtense tab


BS EN 207:2009 beam diameter factor implemented (it is wrong in the published standard!)

Option to reset preferences added


Occasional Flight Zones tab flicker corrected


Support for the revised BS EN 207:2009 added (without beam diameter factor)
Flight Zones Tab added to estimate distraction, glare and flash blindness hazards
Print Tab summaries added which allows printing of calculation details


Support for the revised BS EN 208:2009 added


Advanced Computational Entry (ACE) Aperture calculations tab added.
Pulse calculations tab upgraded to ACE


LaserBee versions 4 and earlier were written in Labview. The need for LaserBee 5 arose when 60825-1 was revised in 2007. LaserBee 5 was then written in Java to fully embody BS EN 60825-1:2007 and BS EN 60825-14:2007.

Versions were numbered 5.x.y where a change in x generally indicates significant functionality added and a change in y indicates a more minor upgrade or bugfix release. The first public version, 5.0.5, was released in February 2009 and purchasers were upgraded to 5.1.0 in July 2009.

LaserBee 6.0.0 was released in October 2014 following the revision of 60825-1 in 2014. (BS EN 60825-1:2014, IEC 60825-1 ed 3.0).
