Page 3: Introduction
262/264 LaserMount User’s Manual · Page 3 Introduction Thank you for choosing the 262/264 LaserMount from Arroyo Instruments. The 262/264 LaserMount is designed for high performance and long term use. The 264 LaserMount integrates a large 120W Peltier cooler for precise control and substantial heating and cooling capacity for your powerful devices. -
Page 4: Installation And Use
Storage of the unit outside the standard storage temperature or humidity rating, or prolonged storage under harsh conditions; • Failure to operate properly. If needed, contact your distributor or Arroyo Instruments for service or repair to ensure the safety of the product is maintained. Installation and Use The 262/264 LaserMount is an easy to use mount. - Page 5 The DB-9 is used for lower power applications, usually no more than 10A, while the 9W4 supports up to 20A operation. Where possible, we recommend the use of Arroyo Instruments laser and TEC cables. Use p/n 1264 TECSource Cable for the temperature controller connection, and LaserSource cable as appropriate for your fixture.

Page 16: Using The Thermistor On Standard Versions
Page 16 · 262/264 LaserMount User’s Manual Figure 7 - Front View of 260 Series Using the Thermistor on Standard Versions The standard version of the 264 LaserMount is equipped with a 10kΩ negative temperature coefficient (NTC) thermistor, specifically, the BetaTHERM 10K3A1. A thermistor works by translating temperature into resistance, with resistance decreasing as temperature increases (hence the ‘negative coefficient’). - Page 17 Steinhart- Hart equation: The coefficients for the BetaTHERM 10K3A1 thermistor are: A = 1.12924x10 B = 2.34108x10 C = 0.87755x10 These are the default coefficients for Arroyo Instruments temperature controllers.

Page 18: Using The Rtd On 150° Versions
(see Operating at High Temperatures, below). For the Arroyo Instruments controllers that support RTD sensors, the default coefficients are not correct for this mount. They must be changed to use the 0.00385 Ω / Ω / °C curve, which has the following coefficients: A = 3.9080x10... - Page 19 0°C), and small Ω/°C. Because of these two factors, the resistance of the cable used to connect to the sensor can become a significant error in the sensor measurement. Most Arroyo Instruments controllers offer two RTD measurement modes: a conventional two wire measurement mode, which is subject to this...

Page 20: Operating At High Temperatures
Page 20 · 262/264 LaserMount User’s Manual Operating at High Temperatures The 150°C version of the 264 has additional requirements that should be considered when operating in the upper temperature range: The voltage requirements of the TEC increase significantly when operating at the higher temperatures, so much so that the standard 5305 or 6300 Series controllers will be voltage limited when controlling the mount. -
Page 21: Laser Diode Protection
Electrostatic discharge and current spikes can be a significant cause of damage to laser diodes, but when proper precautions are taken, these risks can be greatly reduced or eliminated. Arroyo Instruments’ controllers offer state-of-art laser diode protection, but no instrument can fully shield the laser from damage. -
