1. What do the initials AOTF stand for and how does the device operate?
AOTF stands for Acoustic-Optic Tuneable Filter. AOTF is a piece of equipment that operates on different wavelengths where each can be electronically diffracted. Using an aperture, the remainder of the light that is ‘zero order’, will be blocked/stopped and therefore only the required light will be produced at the required wavelength. All the selected light that will be in the form of diffracted and ‘zero order’, is going to be produced at just about a similar angle. The spectral effects, wavelength intensity, the aperture and the other common varieties of a particular AOTF will be highly influenced by the composition of its details.
2. What factors should I consider when buying the AOTF NIR device?
It is important to look for the best, most proficient device available on the market, one that is going to match up to your expectations. The speed of the device is important because the rise time of the device is highly influenced by the speed of the sound beam across the size of the beam of light. It is also important to consider the size of the beams because the larger they are, then the slower the device.
3. What does Acousto-Optics relate to?
Acousto-Optics, usually indicated as AO is the use of the phase-grating structure that is established by sound waves, in a substance to power a light beam being conveyed through the substance. A piezeo (electric) transducer that is joined to the substance forms a sound wave.
4. What is the difference between an AO modular and AO frequency shifter?
The amplitude plays a major role in affecting the signal of light going through it via a modulator. The frequency shifter on the other hand is used to provide a Doppler effect on the beam’s frequency, that is, on the beam going through the AO modular.
5. How does carrier frequency work and what is it?
Carrier frequency is the apparatus that is used to read the numbers of the model back-to-back. It is particularly used to read the beginning number in the model number, while the beam records the movement of the frequency.
6. What are the important aspects that I should observe when purchasing carrier frequency of a Modulator?
It is important to note that a Modulator enhances the process of modulation. This is the generation of the grating, which must be accomplished at a very high speed, for the modulation of the expected rates to be sustained. When it comes to the particulars, it is better to choose a carrier frequency that is approximated to be four times that of the modulation (digital) bandwidth.
7. Apart from the intensity of the diffracted order decreasing when the AO device is tampered, what other factors affect alignment?
In order to achieve the full effect of the acoustic beam, it is important to align the device and ensure the light beam is parallel to the electrode. However, the Brewster Cut devices the direction of the electrode is not affected by the optical faces. The light beam in the device should be equivalent to the electrode to experience the expected acoustic beam impact.
