1.3.2.4 Examples of Custom OEM Thermal and Photodiode Sensor Solutions

In addition to the standard OEM products described above, Ophir has accumulated over 25 years experience in developing products which are tailored to precise physical configurations provided by the OEM customer. These products include custom discs (with or without electronics), specially configured thermalor photodiode-based power sensors, and much more. A number of these special OEM products are shown below.

1.3.3 Pyroelectric OEM Sensors

1.3.3.1 Pyroelectric OEM Sensors - Introduction

Ophir manufactures three main types of pyroelectric OEM sensors:

ֺCompact pyro sensors with no electronics with output connected to the host electronics. Since the energy of pyro sensors is proportional to the peak to valley voltage output and not the maximum voltage output, the user has to take this into account in designing the electronic interface (see below)

ֺPyroelectric sensors identical with standard PE-C sensors but with RS232 or analog output instead of connection to smart sensor

ֺCompact smart PE-C sensors with the electronics in a separate electronics module

Typical output from a non amplified pyroelectric sensor appears as follows:

Ophir non amplified pyroelectric sensor output for repetitively pulsing laser

1.3.3 Sensors

In the example shown above using a non amplified sensor, note that energy is proportional to ΔV and not to the voltage above the zero level. Note also that the peak rapidly decays and therefore the output depends on pulse rate and duration. It follows therefore that in order to measure pyroelectric pulses, the voltage level must be known before the pulse and must also compensate for pulse rate (or work at a low enough pulse rate for the correction to be rendered negligible).

When using a sensor with built-in electronics, typical output appears as follows:

Output from Ophir pyroelectric OEM sensor with built-in signal conditioning

Note that the output voltage is now proportional to the energy and since the voltage is held for a fixed time, the output is much less dependent on pulse rate or duration.

In the above example, the user does not need to perform any signal conditioning but simply has to read the voltage level or get the ouput in digital form to determine the energy. The output is also available in digital form via RS232.

Power Meters and PC Interfaces

Ophir power meters and PC interfaces work on the smart plug principle. This means that almost any Ophir power meter or PC interface can work – plug and play – with almost any of the wide range of Ophir sensors. Ophir power meters are also the most sensitive, lowest noise, most precise calibration units on the market thus giving the untmost performance from our smart sensors.

As for ease of use, only Ophir power meters have smart keys to give the easiest and most convenient user interface. The units also come with a versatile range of software to use seamlessly either with the Ophir software or the user’s own.
