| Introduction: |
These types are compact and light weight, and are suitable for light source to be incorporated in OEM instruments, and for experimental purpose. As aspherical lens is mounted, fixed quasi parallel beam is radiated on ULD Type.
On DPM-P Type, laser focus can be adjusted by turning focus roulette.
On DPM-P Type, APC (Automatic Power Control) circuit is applied, so that it can be used as the constant power light source.
* Warning
Heat radiation is necessary. For example, please fix laser head to aluminum or copper holder. |

|
| Features: |
LDP-M, LDP-MA, LDP-A and LDP-HA Types are designed to radiate laser beam at controlled output by APC circuitry (Automatic Power Control) incorporated in laser head.
Laser beam focus can be adjusted by turning focus roulette. LDP-MA and LDP-HA are equipped with Helicoid type focus adjustment mechanism, so that optical axis deviation is kept at a minimum. (In case of Helicoid type, lens does not rotate on focus adjustment.) On LDP-M, LDP-MA and LDP-A, high NA lens is used as collimator lens, so that high output efficiency is obtained. As LDP-HA is equipped with low NA lens, it is suitable to focus beam at far distance. |

| Introduction: |
UV (375nm), Violet(408nm), Blue violet(440nm) and Blue(470nm) elements are assembled with respective ACC driven laser and temperature control function. As UV to Violet range of wavelength can be detected at the edge of wavelength sensitivity of monitoring Photo Diode, it is difficult to obtain similar wavelength stability to "Red to IR range", even if stabilization is arranged by APC drive feed back.
In order to solve this problem, on our Diode Laser units, power is stabilized by controlling both electric current and temperature.
Hence stable output and wavelength are achieved even at the temperature fluctuating circumstances.
As Diode Laser element can be replaced, it is economical in running cost. |

Standard Drivers are 2A,5A,10A And we are ready to design a further high power type on a customer's requirement. As a high power type Diode Laser element sold in a market can be mounted, if you have specific wavelength and power, we will try to find suitable one among the market.
Reliable power stabilization is achieved by the equipment with thermal control mechanism. As the optical unit in the head is equipped with XYZ adjusting mechanism, an emission angle or focus distance can be freely adjusted.
Diode Laser element can be replaced if Diode Laser element is the same shape. In case of high power, the heat sink is necessary. |
