● The header is available in two sizes. The larger, IR-21, has an 8.6 mm diameter base. The smaller, IR-22, has a 4 mm diameter base. The support pins, which are also the power leads, are hermetically sealed in glass.
● The IR-20 Series is offered in two configurations: the IR-21 and IR-22 have the element mounted horizontally and the IR-21V and IR-22V which have the element mounted vertically.

IR-30 Series
● Active area: 1.8 mm x 1.8 mm
● Emissivity: ~0.75
● Temperature: 950℃
● Voltage: 2.5 Volts (AC or DC)
● Current: 1.7 Amps
● Lifetime: ~25,000 hours
● IR-35 Normalized On-Axis Output:11x the output of the IR-30
● The IR-35 is the IR-30 with a parabolic reflector to collimate the energy.

IR-40
● Voltage: 35 Volts (AC or DC)
● Temperature: 600℃
● Current: 115 mA
● Power: 4.0 Watts
● Active area: 3.5 mm x 2.5 mm
● Emissivity: 0.80
● Lifetime: 3+ years at 600℃, typical
● The IR-40 unit is attached to a TO-5 header with high temperature cement. This unit is also offered without a cap (as an IR-40NC) and with a cap and sapphire window (as an IR-40S).

IR-43
● Voltage: 14 Volts (AC or DC)
● Temperature: 600℃
● Current: 90 mA
● Power: 1.3 Watts
● Active area: 1.5 mm x 1.5 mm
● Emissivity: 0.80
● Lifetime: 3+ years at 600℃, typical
● The IR-43 unit is free standing on a TO-5 header. It requires less power to achieve the same temperature as the IR-40. Without a directly connected mass to draw of heat, it is more responsive.

IR-50, IR-55 and IR-56
● Voltage: 6.4 Volts (AC or DC)
● Temperature: 750℃
● Resistance in the Hot state*: 50 ohms
● Current: 135 mA
● Power: 0.9 Watts
● Cooling Time Constant: 11.5ms
● Heating Time Constant: 35 ms
● Modulation Depth: 50% at 63 Hz, 50% Duty Cycle
● Active area: 1.7mm x 1.7mm
● IR-55: Lamp mounted in parabolic reflector (no window)
● IR-56:As per the IR-55 but with a smaller parabolic reflector allowing operation in a
smaller envelope. 9.1mm x 10.2mm diameter
● Lifetime(constant operation is approximately half these figures):
● 6+ months at 750℃ 10Hz 50% Duty Cycle, typical
● 3+ years at 600℃ 10Hz 50% Duty Cycle, typical
● 8+ years at 450℃ 10Hz 50% Duty Cycle, typical
● * Measured at 5 Hz frequency, 50% duty cycle.

● Current at 750℃: 149 mA
● Power input at 750℃: 1.0 Watts
● Spectral Range: 1 to 20 microns
● Emissivity: 0.8 (in the range of 2 to 14 microns)
● Modulation Depth: 50% at 70 Hz, 25% Duty Cycle

● Lifetime: 100,000h at 450℃; 40,000h at 600℃; 5,000h at 750℃ of operation (10 hertz at 50% duty cycle)
● Output 25-30% greater than the IR-50
● The IR-65 utilizes a collimated Optic to provide more than 12x the on-axis output. The package is 0.5 inches in diameter and 0.65 inches long. FWHM (full width at half max) for the IR-65 is 15°
● As per the IR-65 but has just 36% of the IR-65 size. The package is 0.40 inches in
diameter and 0.36 inches long. And yet it delivers 50% to 75% of the IR-65 on-axis
