The ramifications of these changes are relatively small.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. With the emergence of new biological anis for sub-nanosecond pulses, more precise and less conservative guidance is provided in the new standard for ultrashort pulses down to femtoseconds in the retinal hazard region of 0.

If the document is revised or amended, you will be notified by email. As the voice of the U.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. We have no amendments or corrections for this standard. Need more than one copy? However, technical information on measurements, calculations and biological effects is also provided within the standard and its appendixes. Z1336 should be contrasted with previous generations of laser pointers that were based on HeNe lasers and were generally classified as Class 2.


Flashblindness, afterimage, and glare can occur as a result of exposure to laser pointers and may result absi visual dysfunction that can affect visual-critical activity such as driving or flying. CopyrightLaser Institute of America. This standard is also available to be included in Standards Subscriptions. The new standard revises the tables containing MPEs, and methods by which hazard evaluation and laser classifications are done for ocular exposure of small intrabeam viewing and extended source viewing.

You may delete a document from your Alert Profile at any time. The Control Measures section of the new standard z1136 treats safety issues associated with laser pointers, and provides guidance for the safe use of these products.

The appendix contains numerous examples that illustrate and clarify the application of the new methodology. Proceed to Checkout Continue Shopping. Ahsi Class 1 category is therefore significantly expanded for those lasers.

Guidance is also offered in the use of laser eyewear in conjunction with ultrashort pulses. The ANSI Z specifies sign dimension, lettering size, color, and other important sign design elements. Subscription pricing is determined by: Already Subscribed to asni document.

The great proliferation of these devices has made it more likely that individuals who are not familiar with appropriate safety precautions would use them. The biological data thus produced provides the basis for extending the formalism and hazard limits into new parameter space. In the past several years the use of laser pointers has proliferated significantly.


Three new classes of lasers are being created 1M, 2M and 3R. Available for Subscriptions Available in Packages Standard is included in: For pulses shorter than 10 —9 seconds, the guidance was to employ the MPE for 1 ns. Once adopted by ANSI, corresponding changes will be have to be made in the Control Measures and Measurement sections to account for the added wnsi. The new standard also facilitates the methodology of dealing with ani and extended sources.

Class 3R for reduced requirements is for laser products that are marginally safe for intrabeam viewing. Join or Renew Members Only. Visit the LIA website at http: Your Alert Profile lists the documents that will be monitored. Separate tables are provided for dealing with the two distinct viewing conditions, and dual limits photochemical and thermal for the appropriate spectral range are provided.

The new 11 symbol is introduced into both the anzi and “Danger” signs. Currently few differences exist between the two standards.

They are routinely used in demonstrations, alignment, educational, and numerous other applications.
