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.

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.
