What is a spectrometer used for?

Optical splitters are passive devices, also known as optical splitters. They do not require external energy, as long as there is input light; the optical splitter consists of entrance and exit slits, reflectors and dispersion elements. Its function is to separate the required resonance absorption lines; the key component of the spectrometer is the dispersion element, and now commercial instruments use gratings.

What is the spectrometer used for?

Optical splitters are passive devices, also known as optical splitters. They do not require external energy, as long as there is input light. The beam splitter consists of entrance and exit slits, reflectors and dispersion elements. Its function is to separate the required resonance absorption lines. The key component of the spectrometer is the dispersion element, and now commercial instruments use gratings.

Classification

1) After the light enters the spectrometer, ordinary light can be divided into the following three categories according to wavelength:

Near UV ): 200-380nm.

Vacuum UV (vacuumUV): 10-200nm.

Extreme UV, Extreme UV: 1-10nm.

2) From the perspective of human health and environmental protection, it can also be divided into UVA (315~400nm), UVB (280~315nm), and UVC (below 280nm).

3) Another classification method is single-mode and multi-mode.

Single mode: 1310nm. Multimode: 850nm.

There are three general interfaces for optical splitters, one is LC, one is FC, and the third is SC.

Composition

The atomic absorption spectrometer does not have high requirements on the resolution of the spectrometer. It was once able to distinguish the third line of nickel Ni230. 003, Ni231.603, and Ni231.096nm are used as standards, and Mn279.5 and 279.8nm are later used to replace the Ni three lines to verify the resolution. A grating is placed after the atomizer to block all unwanted radiation from within the atomizer from entering the detector. [1]

Use environment

Spectrometer application environment requirements: -30~65℃, RH 5-95%.

If the product is used outdoors (such as sewers/outdoor cabinets), it needs to be mold-proof, protected from direct sunlight, too humid, or too close to other heat sources. In some areas, it also needs to be protected from salt spray, etc.

It is best to add optical fiber and other protective measures to prevent rat bites.

The location of the optical splitter is not easy to be collided with other objects and difficult to be reached by people to avoid being damaged by humans;

Pigtail support tensile resistance: less than or equal to 5 Newtons.

Waterproof design: Must be placed in a waterproof and dustproof sealed container.

Electricity-proof design: Anti-lightning strike and high-voltage power grid service life: greater than or equal to 10 years.

Outdoor optical splitter can be installed in manholes, roadsides, telephone poles, etc. It is waterproof and anti-corrosive.
