ILX Lightwave Corp. has released the LDT
53500 series laser diode thermoelectricchillers. The two models available offer185- and 370-W cooling capacities as wellas temperature control over the range of; 5 to 45 °C. The heat exchanger designand optimized PID control loop constantsprovide temperature stability of ±0.1 °C atthe water outlet. The devices are equippedwith multiple interlocks, a removable frontpanel, external temperature sensing and aUSB interface.
The 20-3001 NC noncrystallizing epoxy potting andencapsulating resin introduced by Epoxies Etc. is alow-viscosity system thatforms a bubble-freeglasslike finish whencured. Containing no solvents or fillers, it is available in black or clear andin 50-, 75-, 200- and 400-ml dual-barrel syringes, or in quarts, gallons and 5-gallon pails. Mix ratioby volume is 1:1 and by weight, 100: 83. Operating temperature is from– 50 to 150 °C, and tensile strength is 5700 psi.
