+==== Safety Information ====
+<WRAP center round important 60%>
+The D2-100 is only specified for use with the Vescent D2-105 laser controller, and with cables provided by Vescent.
+</WRAP>
+The D2-100 is a Class 3B CW laser product under the guidelines provided in IEC 60825-01:2014. It has no serviceable parts, and should not be disassembled in the field under any circumstance. Viewing of the beam, either directly, with viewing optics, or from a specular reflection can cause damage to the eye, and should be avoided.
+The D2-100 is available in many wavelengths, listed above, as well as in a high powered configuration. The maximum specified output of any D2-100 is 200mW under normal operating conditions. However, if provided with too much current, some of the high powered (-HP1) lasers can reach 300mW before experiencing critical optical damage. The beam divergence is < 0.08° in both x and y.
+The Maximum Permissable Exposire (MPE) for the D2-100 is 14.45 W*m<sup>-2</sup>, calculated with a >10s exposure time, and the Nominal Ocular Hazard distance is roughly 100m. Proper eye protection for the D2-100 is highly wavelength dependent. We recommend [[https://noirlaser.com/lasershields?input1=780&input2=0&input3=0|this]] online tool, provided by NoIR, and an OD value of at least 3+ for the selected wavelength when choosing the correct eye protection.
+There are four safety stickers present on the D2-100. The first, located on the side of the isolator module, is the explanatory sticker, which states the classification of the laser, and several safety instructions. It reads: "Invisible laser radiation avoid exposure to beam class 3B laser product".
+<imgcaption safety_sticker|Reproduction of Explanatory label on the D2-100. \>{{ :d2:d2-100:sticker.png?200 |}}</imgcaption>
+On the side of the isolator module opposite the explanatory sticker is a sticker which lists the maximum possible output of the laser in mW, the wavelength of the laser, and the name of the IEC certification standard to which the laser adheres.
+<imgcaption IEC_sticker|Reproduction of second Explanatory label on the D2-100.>{{ :d2:d2-100:needed_sticker.png?200 |}}</imgcaption>
+On the top of the D2-100, near the laser aperture, is a "Laser Aperture" sticker.
+<imgcaption aperture|Reproduction of Laser Aperture sticker on the D2-100.>{{ :d2:d2-100:aperature.png?200 |}}</imgcaption>
+Finally, on the sliding beamstop adjacent to the laser aperture, is a triangular laser radiation warning sticker.
+<imgcaption triangle|Laser Radiation Warning sticker on the D2-100.>{{ :d2:d2-100:triangle.png?200 |}}</imgcaption>
+There is only one laser aperture on the D2-100, located on the front with the isolator as shown in (<imgref DBR_laser>).
+Safe operation of the D2-100 necessitates that a compliant laser driver be used to supply a current to the diode. It is important to always correctly set the current limit on any laser driver before energizing the laser system. The D2-100 is a Cathode-Ground laser, and requires a DC current between 0mA and 500mA((Specific current for each laser supplied with test documentation)) to be safely turned on. The connector used to supply current to the D2-100 is a female SMA, which requires a male SMA cable for compatibility.
