• Large analogue display • Working range 100 µW - 3 W • Mains and battery operation • Integrated charging unit • Battery life time: >300 hrs • Time constant: 1 sec • Solid metal case • Outer dimensions: 160 x 180 x 70 mm³ This read out unit is designed to measure the output power of different lasers in combination with a thermophile head. The maximum power is limited by the power head used. Normally, the time constant of a power head is in the region of 15 to 25 seconds. Use of the read out unit enables reduction of the time constant of the whole measurement system to one second. A special adapter is required for connecting the head (15pin Sub-D to BNC). This adapter is used for matching sensitivity and thermal characteristic. The LM 100 is equipped with a rechargeable battery and charging unit. The LM 100 can be operated either using the mains supply or the rechargeable built-in batteries. This makes it versatile and adaptable to most applications. The batteries are automatically charged when the instrument is plugged into the mains AC power supply. The batteries can also be charged when the LM 100 is turned off. The charging circuit prevents the batteries from being overcharged. The state of the batteries and the charging circuit is displayed by two LEDs.
