DESCRIPTION
The VIEW-IT® Ultraviolet Detector product line features vari-
ous substrates and target sizes designed to convert invisible
ultraviolet light to visible red light. A very convenient tool
for viewing ultraviolet light sources, laser beam shape, mode
structure, and alignment. These tools provide an unlimited
period of viewing both pulsed and continuous-wave sources
operating between 190-390nm.
LASER SAFETY
Depending on the operating parameters of the laser source
and the potential for MPE (Maximum Permissible Exposure)
limits to be exceeded, there may be a signicant risk of eye
injury. Under such conditions, we recommend the use of ap-
propriate laser protective eyewear. Laser protective eyewear
must be evaluated in accordance with ANSI Z136.1 standard
for the Safe Use of Lasers.
INSTRUCTIONS
1. Calculate your laser beam power density and verify a
location that is safe to use the VIEW-IT® UV detector.
2. Never use the product in a location above the maximum
laser damage threshold as damage may occur to the VIEW-IT®
UV detector.
3. Wear appropriate safety eyewear for your application,
place the VIEW-IT® UV detector target in the path of the
infrared light source being careful not to reect it towards
your face or others.
4. VIEW-IT® UV detector will illuminate with no charging or
external power. Simply apply the minimum required sensitivity
to the target area for viewing.
5. Reected 620-660nm red visible light conversion will be
0.4~1% of incoming ultraviolet light.

COMPLIANCE
This product line is RoHS, Reach and LaserSmart® compliant.
WARRANTY
Kentek warrants VIEW-IT® products to be free from defects
caused by faulty material or poor workmanship. Liability
under this warranty is limited to the obligation to repair or,
at Kentek’s sole option, to replace without charge, any part
found to be defective under normal use within one year
from date of invoice.
Kentek must receive written notication within the warran-
ty time period stating what defects were noticed, or what
problems occurred with this product. This warranty shall not
apply to items which have been subject to abuse or mis-
use after delivery, or to items which have been altered in a
means not authorized by Kentek personnel.
SPECIFICATIONS
1. Spectral sensitivity: 190-390nm.
2. Minimum sensitivity: 1mJ or 1mW/cm.
3. Maximum damage threshold: 1 joule/cm nanosecond
pulses, 10 joules/cm micro/millisecond pulses, 30 watts/cm
continuous wave.
OTHER HAZARDS
Evaporation of the composition may occur upon interaction
with strong infrared radiation with energy uency of more
then 100J/cm at pulse durations between 30 nanosecond-40
milliseconds. Also, excretion of hydrogen sulde (HS) under
inuence of acidic environment with pH 2-3 may occur. Use
the VIEW-IT® tool in a well-ventilated area.
PREVENTIVE MAINTENANCE
Recommended daily inspection of the product.
• Verify that the target surface hasn’t been damaged by the laser.
• Make sure the target is clean before placing it in the path of the
laser beam.
