TL-445P portable laser evidence discovery instrument

1. Product introduction:
The British TL laser biological detection instrument (blue light 445nm) has a super discovery function for blood stains, blood, sperm spots, sweat spots, urine, hair, dandruff, exfoliated cells, bone and tooth fragments and other biologically active substances; no treatment is required, And there is no damage to its biological activity, which can fully guarantee the authenticity, integrity and biological activity of the original information of the material evidence. At the same time, it has the function of directly detecting gunshot residues, fibers, etc. and potential fingerprints.


2. Advantages and characteristics:
    1. Non-destructive inspection: the original real information can be directly obtained, and there is no damage to the biologically active substance (DNA).
    2. It has a super discovery function for biologically active ingredients, such as blood stains, blood, sperm spots, sweat spots, urine, hair, dandruff
    3. Exfoliated cells, bone and tooth fragments, etc. have stronger discovery capabilities than conventional light sources and high-power LED light sources.
    4. It has direct detection function for sweat and oily fingerprints, far superior to other light sources.
    5. Hidden information search, the original and true information can be found in the processed or covered material evidence.
    6. Significant clarity, this section is super clear; high-quality high-power pure color laser light source, other non-laser light sources can not be compared.

3. Technical parameters:
    1. Laser technology, wavelength: 445±2nm; uniform spot
    2. Host output power: 12W
    3. Device startup: start directly, turn on the power and use it directly without preheating
    4. Laser service life: more than 20,000 hours
    5. Design service life: more than 20,000 hours
    6. Size: 25cm(L)x10cm(W)x5cm(H)
    7. Light weight: less than 1.8 kg
    8. Especially suitable for on-site investigation
 
4. Structure part:
    1. Portable design, laser excitation control switch on the handle, very convenient to use.
    2. The handle has a power indicator and laser excitation indicator.
    3. With a strap, it is very convenient for police officers to carry.
    4. There is a laser power adjustment knob on the host, which can adjust the laser output power.
    5. The equipment has a computer control system, a computer display screen, and a number. The battery signal recovery system, when the external temperature is too high or the standby time is too long, or the device is too high, the device itself has its own adjustment device to directly adjust the power to the available power. The battery displays the power, the alarm system when the remaining battery capacity is insufficient, and the alarm system when the environment is not suitable for laser light source equipment.
    6. The output mode has two forms of digital and analog, which can be intuitively converted, and can be displayed intuitively. It has a high-frequency power supply and can be directly converted to high-frequency output when the battery power is weak to maintain the observation effect.
