Lens (For thru-beam type fiber)

Designation	Model No.	Description
Expansion lens (Note 1)	FX-LE1		Increases the sensing range by 5 times or more. ・ Ambient temperature: -60 to +350 ℃ -76 to +662 ℉ (Note 2) ・ Beam dia: ø3.6 mm ø0.142 in Sensing range (mm in) [Lens on both sides]
Super-expansion lens (Note 1)	FX-LE2		Tremendously increases the sensing range with large diameter lenses. ・ Ambient temperature: -60 to +350 ℃ -76 to +662 ℉ (Note 2) ・ Beam dia: ø9.8 mm ø0.386 in Sensing range (mm in) [Lens on both sides]
Side-view lens	FX-SV1		Beam axis is bent by 90°. ・ Ambient temperature: -60 to +300 ℃ -76 to +572 ℉ (Note 4) ・ Beam dia: ø2.8 mm ø0.110 in Sensing range (mm in) [Lens on both sides]

(Note 1):	Be careful sure to use it only after you have adjusted it sufficiently when installing the thru-beam type fiber equipped with the expansion lens, as the beam envelope becomes narrow and alignment is difficult.
(Note 2):	Refer to "Fiber page" for the ambient temperature of fibers to be used in combination.

Vacuum-resistant lens (For thru-beam type fiber)

Designation	Model No.	Description
Expansion lens for vacuum fiber (Note 1)	FV-LE1		Sensing range increases by 4 times or more. ・ Ambient temperature: -60 to +350 ℃ -76 to +662 ℉ (Note 2) ・ Beam dia: ø3.6 mm ø0.142 in Sensing range (mm in) [Lens on both sides]
Vacuum-resistant compact side-view lens (Note 1)	FV-SV1		Beam axis is bent by 90°. ・ Ambient temperature: -30 to +300 ℃ -22 to +572 ℉ (Note 2) ・ Beam dia: ø3 mm ø0.118 in Sensing range (mm in) [Lens on both sides]
Vacuum-resistant side-view lens (Note1)	FV-SV2		Beam axis is bent by 90°. ・ Ambient temperature: -60 to +300 ℃ -76 to +572 ℉ (Note 2) ・ Beam dia: ø3.7 mm ø0.146 in Sensing range (mm in) [Lens on both sides]

(Note 1):	Be careful sure to use it only after you have adjusted it sufficiently when installing the thru-beam type fiber equipped with the expansion lens, as the beam envelope becomes narrow and alignment is difficult.
(Note 2):	Refer to "Fiber page" for the ambient temperature of fibers to be used in combination.
