BHPA650-L is listed in historical product information as a PMMA linear Fresnel lens. The reference sheet gives a 400 × 320 mm outline, 2 mm thickness and 0.5 mm groove pitch. Current specifications and availability require confirmation.
No. The historical focal-length field reads 650, but its unit has not been confirmed. Do not treat it as a verified 650 mm specification. Request a current drawing and confirm both the unit and measurement conditions before selecting this model.
Describe the direction and length of the desired line, the source geometry, available mounting space and receiver position. Confirm the groove direction and clear aperture in the drawing. The model name alone does not establish line width, concentration ratio or suitability for a solar or illumination system.
