Peak 2020 Enlarging Focuser

Peak 2020 Enlarging Focuser

Enlarging Focusers 2020 and 2030

These focusers are auxiliary instruments which ensure extremely sharp focusing of your photo-enlarger not only at the picture center portion but also at any position within the picture area. With the aid of these focusers, you will be able to demonstrate the full performance of your enlarger and obtain pictures of unparalleled sharpness.

Construction and Principles of Focusers
The focuser mainly consists of a mirror, loupe and pattern plate. The bottom surface of the pattern plate and the basement surface of the focuser are adjusted so that they will be in positions accurately symmetrical to the mirror. Therefore, when the focus of the enlarge is adjusted to cause the enlarged image of the negative to correctly focus on the bottom surface for the pattern plate, the enlarged image of the negative is correctly focused on the photographic paper, when you remove the focuser from the easel.

Even if you place the focuser at a position deviated from right below the optical axis of the enlarger, there will be no change in obtaining the correct focusing.

2020 (Model II)
This model has the same basis design as Model I. Through the use of the special-design wide-field loupe, focusing is possible within the range in which the optical axis if the enlarger lens forms an angle of about 20° with the optical axis of the loupe, while the loupe and pattern plate are being securely fixed. For the body of this model, glass fiber impregnated resin is used.

Eye-piece: 10x, 3-groups, 4-elements
Angle: 20°
Mirror: 53 x 27mm
Size:65 x 140 x 140mm

Accessory: BG filter (optional)
Use of the BG filter.
When you want to obtain more correct enlarging for the black and white film, use the focuser after fitting the BG filter to its eyepiece. The use of this filter will permit the coincidence between the wavelength sensitive to your eyes and that to be enlarged..

Replacement mirrors and eye cups are available.
