NÁVOD K POUŽITÍ VÝROBKU

Zavedení:

• Power Technology’s IR viewers convert otherwise invisible infrared radiation into a visible green image. These devices support both CW and pulsed sources down to sub-microsecond regimes without external synchronization.
• Applications (typical): IR laser alignment; semiconductor wafer inspection (with microscope adapter); photo processing; thermal/industrial inspection; forensics; food sorting; fluid inspection; and biological illumination tasks.

Instalace:

• Mounting (both models): Use the ¼-20 tripod interface for hands-free operation.
• Lens/Eyepiece: Install the supplied C-mount objective, then set coarse focus on the objective and fine focus at the eyepiece. (Locking screws as shown in figures.)
• Filters (NIR use): Fit the IR cut-off/attenuation filter for near-IR viewing; when inspecting reflections, prefer a metallic diffuser. Paper tends to absorb/attenuate IR.

Operace:

• IRV3: Charge via USB-C at ≤ 5 VDC / 500 mA. (Do not exceed this rating.) An internal Li-ion pack powers the tube; after switching OFF, residual charge may keep the screen lit briefly—this is expected.
• IRX3: Install two 3.6 V 18650 Li-ion cells with correct polarity, close the cover securely, then power via the ACTIVATE button. Observe the LED battery indicator: solid = full, slow-flash = OK, fast-flash = low.
  • Caution – Direct exposure: Avoid exposing the tube face to concentrated radiation; permanent sensor damage can occur. Important – These viewers are for indirect beam observation. Do not use for direct beam viewing or to look for“mid-air” beams. View a diffuse target (IR card, matte metal, etc.)—over-exposure can damage the tube or reduce photocathode response.

Operating Procedure & Control Description: IRX3 (Figure 1)

1. Power: Insert two 18650 cells, close the cover, and press ACTIVATE.
2. Brightness: Use screen brightness buttons to set a comfortable luminance without blooming.
3. Focusing & Iris: Rotate the focus ring to sharpness; adjust the diaphragm (iris) for contrast and depth; set eyepiece focus to your vision.
4. Filters & Targets: Use the cut-off filter for NIR; prefer metallic diffuse targets over paper.
5. Battery Status: LED solid = full; gradual flash = acceptable; rapid flash = low. Auto power-off after inactivity (see data sheet).

Power/Charge: If needed, connect USB-C (≤ 5 V/500 mA). Press the ON/OFF button to start. Residual screen glow after power-down is normal.

1. Focusing & Iris:
   • Rotate the objective focus ring to bring the scene to focus (1×: F/1.4 25 mm; 2×: F/1.8 50 mm).
   • Adjust the iris to balance brightness vs. depth of field; tighten the iris set screw after adjustment.
   • Fine-tune the eyepiece focus to your vision.
2. Filters & Targets: For NIR, install the IR cut-off filter. View a diffuse reflector (e.g., IR card or matte metal).
3. Tripod Use: Thread onto ¼-20 tripod for stable, hands-free operation. Notes on Visualization: For wavelengths across the IRV model family (IRV1300/1700/2000), detection thresholds vary with wavelength and optical configuration; observing a diffuse target at 1 m typically requires the minimum irradiances indicated in the technical curves.

Troubleshooting (Both Models)

• Image too dim: Open iris moderately; verify correct filter; increase target reflectivity (matte aluminum card); ensure battery charge (IRX3 LED status).
• Blooming/saturation: Stop down the iris; add neutral density attenuation for very bright sources (IRX3 accessory ND filters).
• Cannot see free-space beam: Use a card/metallic target; do not attempt to “look into” the beam path.

Údržba a servis:

• These products contain no user-serviceable parts. Keep optics clean and dry.
• Use clean compressed air first; if needed, clean glass carefully with alcohol (isopropyl) on a lint-free swab.
• Avoid solvents on plastics or painted surfaces.
• Handling: Protect from mechanical shock and moisture ingress.
• Battery safety (IRX3): Follow local regulations; keep out of reach of children; never expose cells to heat/flame.

Warranty and Repair Return Policy:
No return will be accepted without a factory-issued RMA number clearly marked on the package. Collect/COD returns are not accepted. For warranty returns, PTI coversoutbound shipment to the customer after repair. When requesting an RMA, provide a model, serial number(s), and a concise problem description. Opening or modifying the viewer outside documented procedures may void the warranty and can require re-certification under 21 CFR 1040.10/.11.
Laser Safety (Read Before Use):

• Use controls and procedures only as specified to avoid hazardous radiation exposure.
• Optical instruments increase eye hazard; never aim sources toward people; avoid eye-level beam paths.
• Always wear appropriate, wavelength-rated protective eyewear for the source under test.

Notes on Performance & Best Practices:

• Target choice dominates visibility: Use matte aluminum/ceramic IR viewing cards or rough metal, not paper, to maximize SNR.
• Keep irradiance within the tube’s comfort zone: If the scene blooms, stop down the iris and/or add ND attenuation (IRX3 accessories include ND filters).
• Free-space beams: Don’t rely on scattering; use projection at 1 m and consult the model’s minimum power-density vs. wavelength curves for realistic expectations.

POWER DENSITY

• Approximate minimum power density required to view an infrared laser beam from a distance of one meter:

IRX3 Performance Charts: Minimum Power Density & Brightness Levels

Minimal Power

• densityThreshold power density dependence on wavelength.
• The threshold power density is defined by measuring a laser beam spot on a paper, which exhibits 20% of the overall brightness (calculated a 255 x in contrast to the background.
• The measurements were taken with the viewer positioned 1.15 meters away from the piece of paper.

Úrovně jasu

• Normalised brightness dependence on power difference from the minimum value.
• The power level of 0 signifies the theoretical minimal value at which the laser beam spot becomes observable on a piece of paper.
• It’s worth noting that the viewer exhibits lower sensitivity to laser light at 1450nm compared to 1550 nm or even 1900nm.
