DESCRIPTION
The NV4V31MF is a blue-violet laser diode with a wavelength of 405 nm. A newly developed LD chip structure
achieves a high optical power output of 175 mW (CW) at up to 85°C. The NV4V31MF can provide excellent linearity
from low to high output at high temperatures, and reduces the unevenness of beam divergence.

NOTES ON HANDLING (UNIT: mm)
1. Recommended soldering conditions
• Peak Temperature
350°C or below
• Time
3 seconds or less
• Soldering of leads should be made at the point 2.0 mm from the root of the lead
• This device cannot be mounted using reflow soldering.
2. Usage cautions
(1) Take the following steps to ensure that the device is not damaged by static electricity.
• Wear an antistatic wrist strap when soldering the device.
We recommend a strap with a 1 MΩ resistor.
• Make sure that the work table and soldering iron are grounded.
• Make sure that the soldering iron does not leak.
(2) Do not subject the package to undue stress.
The package has a tensile strength of 1N.
Do not exceed this rating. Also, avoid bending the leads as much as possible.
If the leads must be bent, bend them only once, making sure to anchor the base of the lead.
(3) Do not allow the glass window of the package to become scratched or dirty.
Also, do not subject the glass window to external force.
(4) Be sure to attach a heat sink to sufficiently dissipate heat.
(5) Use the device as soon as possible after opening the aluminum moisture barrier bag.
