 Handling
 Installation method
*1 WD indicates the distance from the tip of the lens to the workpiece. Changing the
magnification changes this distance.
*2 The resolution indicates a theoretical value calculated at 550 nm.
*3 The depth of field is a theoretical value calculated with an effective f-value of 16 and
a circle of least confusion of 40 μm. This varies depending on the f-value.

Safety Precautions
CAUTION
It indicates a hazardous situation which, if not avoided, could result
in minor or moderate injury.
NOTICE NOTICE
It indicates a situation which, if not avoided, could result in product
damage as well as property damage.
It indicates additional information on proper operation.
Tips on Correct Use
CAUTION
Do not look at light sources through the lens. Doing so may cause
eye damage.
NOTICE NOTICE
• Locations where the CA-LMHE0510 is exposed to direct
sunlight.
• Locations where the ambient temperature exceeds or drops
below the specification range, or where the temperature
changes rapidly.
• Locations which are poorly ventilated.
• Locations where the relative humidity drops below 35% or
exceeds 85% RH, or where condensations occurs.
• Locations where there are corrosive gas or flammable gas.
• Locations where there are much dust, sodium, or iron powder.
• Locations where water, oil, or chemicals may splash onto the
CA-LMHE0510.
• Locations where the CA-LMHE0510 may be directly subjected
to vibration or impact.
NOTICE NOTICE
• In case of transportation, use the same packaging as when the
unit was delivered to avoid damage.
• Take care not to dirty the surface of the lens and do not touch it
with your hands.
• If the surface of the lens is dirty, clean it using a commercially
available lens cleaning kit.
NOTICE NOTICE
• When installing this product, be sure to fix the camera side and
the lens side in place at the locations indicated (as shown in the
dimensions diagrams).
• Never fix in place only the camera or the lens, as doing so may
lead to the lens falling off of the camera, which may lead to
accidents, failures, and damage.
• To fix the lens in place, apply uniform pressure at the indicated
locations. Never fix the lens in place at locations other than
those indicated or use a method that applies pressure in a
single location such as a setscrew. Doing so may lead to
product failures or damage.
• This is a precision instrument, so if you will use this product in
an environment that will subject it to direct vibrations or
impacts, implement appropriate vibration proofing
countermeasures. Continually using this product in an
environment that subjects it to vibrations or impacts may lead
to product failures or damage.
• If you will attach this product to a piece of equipment, use an
insulated attachment base or similar device to ensure that this
product is insulated from the equipment. The lens and camera
are grounded through their frames, so installing these products
without guaranteeing insulation in a location in which electric
potential differences and noise are present may lead to
equipment damage and malfunctions.
