The HTL EKE/AL (a.k.a. L1090, 9596ER) is a 21 V / 150 W MR16 Aluminum‑Reflector Halogen Lamp with GX5.3 base for fiber‑optic illuminators, microscopy, and spectroscopy. Forward projects visible + IR (≈400–2100 nm) for extended spectral output vs. cool‑beam/dichroic types. It is commonly sold as alternative part numbers: L1090, EKE/AL EKE/ALUM, 62037 9596ER, EKE/ER, EKE/Alum, and EKE/Aluminum. Typical life 200 h. Made in Japan.

Why choose the AL / ER variant

• Aluminum reflector (ER/AL) sends IR + visible forward → higher NIR throughput into fiber bundles, ideal for spectroscopy, NIR imaging, and materials inspection.

• Drop‑in fit for fixtures that specify ANSI EKE (21 V, 150 W, GX5.3). Always verify thermal requirements; AL reflectors run a warmer beam than dichroic “cool‑beam” lamps.

• Tight filament (CC‑6) for good coupling into 3–8 mm fiber bundles.

Note: EKE/AL  is not appropriate if application demands a cooler beam on the sample.  Consider using the standard dichroic reflector EKE instead.

FAQs

Q: How is EKE/AL different from a standard EKE with a dichroic reflector?
A: AL (ER) reflectors send IR forward; dichroic reflectors pass most IR out the back (cool‑beam). Choose AL when you need NIR throughput to the workpiece or fiber.

Q: Will this fit my Mi‑150 or FOI‑150?
A: If your illuminator specifies an ANSI EKE lamp (21 V, 150 W, GX5.3), this lamp fits. Always observe heat management guidelines when switching from a dichroic to an AL reflector.

Q: What spectral range can I expect?
A: Broadband visible with strong NIR content forward (≈400–2100 nm). Exact output depends on the illuminator optics and filters used.

Q: What is the typical lifetime?
A: Around 200 hours at rated voltage; usage cycles and vibration can affect this.

Q: Country of origin?
A: Japan.
