About Us

In order to design and manufacture programmable optometrical, op-

tomechanical and optoelectronical devices, the science-based compa-

ny, ASHA Beam Prole, was established in 2016.

ASHA has been able to design a wide range of devices, relying on

indigenous capability and knowledge. Also, since being calibratable is

essenal for measuring equipment, clients can carry out their period-

ical calibraon.

Field of activity

The main eld of acvity of this company is the design and produc-

on of laser, opcs and photonics equipment and can be categorized

in the following topics:

»Diode laser driver

»Laser diode stabilizer

»Laser Parameters measuring equipment such as Power Meter, Beam Pro-

ler, and Ultra-fast Detector

»Lithographic masks

»Linear posioner with stepper motor driver

»Calibraon of Power Meters and beam prolers

»Design and producon of soware to facilitate the use of electro-opc

and optomechanical programmable equipment

Main features

Introduction

Measuring the output of light sources is very important. For exam-

ple, the opcal power of medical lasers is very sensive and can cause

irreparable damage if the funcon of the device goes out of its proper

range. In experimental and research applicaons, it is always neces-

sary to measure the output of laser sources. In addion to the above,

it is crucial to pay special aenon to the necessity of calibraon of

industrial and military laser equipment.

Hence, the semiconductor power meter is designed for high preci-

sion laser applicaons. Producons of this company can well meet the

needs of the scienc and industrial community in the eld of power

metering.

The semiconductor power meter is designed for high precision laser
