ZYGO 7702 8070-0102-35 Laser Head

Core parameters

1. Basic model identification

Complete model: ZYGO 7702 8070-0102-35

Belonging configuration group: The document clearly classifies it as "Configuration 31/32/35/36" and shares the size design logic of this configuration group with other models in the same group (31, 32, 36) (specific installation dimensions need to be confirmed with the attached drawings, and the document indicates that the key dimensions of this group include 458.9 mm, 124.0 mm, 72.0 mm, etc.).

2. Key performance parameters

output power

The power of other models in the same series is divided into two categories:>400 µ W (31, 33) and>525 µ W (36). This model should be based on the manufacturer's measured data

Beam diameter

6 mm

Consistent with models 31 and 33 in the same series, it belongs to a larger beam diameter specification and is suitable for scenarios with specific requirements for spot size

Installation method (Mount)

The 31 and 36 models in the same configuration group are "Narrow" (narrow installation). The compatibility of this model can refer to this commonality, but the confirmation result from the manufacturer shall prevail

Shared features (based on the commonality of ZYGO 7702 series)

As a member of the 7702 series, the 8070-0102-35 model defaults to following the unified technical standards and design specifications of the series, with the following core shared features:

1. Laser technology and safety attributes

Laser type: Helium Neon laser, continuous wave (CW), heterodyne, linearly polarized design, ensuring the stability and polarization consistency of the output beam.

Safety level: Class II laser, fully compliant with NCDRH (National Committee for Laser Safety and Standards) regulations. During normal operation, the blink reflex of the human eye can provide basic protection, but it is still necessary to avoid prolonged direct viewing of the beam.

Wavelength and frequency characteristics:

Nominal vacuum wavelength: F1 (vertical polarization) 632.991501 nm, F2 (horizontal polarization) 632.991528 nm, completely consistent with other models in the series;

Wavelength stability: 0.005 ppm/1 hour, 0.01 ppm/24 hours, wavelength lifetime accuracy ± 0.1 ppm, meeting the strict requirements of high-precision measurement for wavelength drift;

Frequency difference: 20 MHz ± 1600 Hz, ensuring frequency consistency in heterodyne application scenarios.

2. Physical and electrical specifications

Physical characteristics:

Weight: 5.5 kg, consistent with all models in the series. When handling and installing, attention should be paid to load-bearing and stable placement;

Material: The casting is made of aluminum alloy (ensuring structural strength and heat dissipation), and the narrow leg (if applicable) is made of Ultem 2400 material (with temperature and aging resistance);

Cable clearance: nominal 135 mm, sufficient cable space should be reserved during installation to avoid cable compression affecting equipment operation.

Electrical requirements:

Power requirements (maximum):+15 VDC ± 0.5 V (current 2.1 A), -15 VDC ± 0.5 V (current 1.2 A), must use a dedicated power supply that meets the voltage and current range, overload power supply is prohibited;

Power consumption: Maximum 39 W during operation and 50 W during preheating. It is necessary to ensure that the power supply line can withstand peak power consumption and avoid overheating of the line.

3. Environmental adaptation and operational stability

Environmental tolerance range:

Working temperature: 10-30 ° C, working humidity: 0-90% (no condensation);

Non working temperature: -40-75 ° C, non working humidity 0-90% (no condensation), suitable for multi scenario storage and transportation;

Impact resistance (non working state): It can withstand an impact of 11 milliseconds and 40 grams in all three orthogonal axis directions, reducing the risk of damage during transportation.

Operational stability indicators:

Beam pointing stability: ＜ 0.5 arc/° C, can effectively control beam offset when temperature changes, ensuring measurement accuracy;

Power on response time: The typical output time is less than 10 seconds (maximum value is 70 seconds), the typical wavelength stabilization time is less than 10 minutes, and it can quickly enter a stable working state after power on.
